What locals say

Synthesized from upvoted comments on each city's subreddit.
Istanbul

Living in Istanbul means daily life is layered with history, congestion, and constant visual drama. People who live here seem to move between beautiful waterfronts, old neighborhoods, crowded transit, and a cityscape that many both love and complain is being overbuilt. The city feels energetic and sociable, with a lot of casual help from strangers, but also prone to friction around traffic, taxis, crowds, and occasional safety concerns. At its best, it feels like a place where there is always something to see, eat, or photograph; at its worst, it can be exhausting, loud, and messy.

  • Overdevelopment / ugly new buildings3
  • Crowding in tourist and transport areas3

London metropolitan area

London feels busy, expensive, and highly connected, with neighborhoods that can feel like separate cities depending on where you live and work. Daily life often means managing long commutes, crowded transport, and high housing costs, but also having enormous choice in jobs, culture, food, and services. The city can be anonymous and fast-paced, yet it is easy to find a niche: a local pub, a park, a market, a late-night takeaway, or a community built around work, sport, or culture. It rewards people who like constant activity and variety, but it can wear down anyone looking for space, quiet, or a simple, cheap routine.

Common complaints
  • Housing costs and rent5
  • Crowding and transport strain4
  • General cost of living4
  • Distance and commute fatigue3
  • Weather gloom and lack of sunlight3
Common praises
  • Unmatched job and career opportunities5
  • Public transport reach5

Food & nightlife

Istanbul
Food

Istanbul’s food scene comes across as abundant, cheap-to-midrange, and hard to stop sampling. Posts mention iskender kebap, kokoreç sandwiches, baklava, lokum, künefe, kabak tatlısı, and endless tea breaks, with many visitors leaving full and slightly overwhelmed. Neighborhood food culture seems very local and specific: people name particular places in Kadıköy or random street-side snacks rather than talking about polished fine dining. The tone suggests that eating here is part of daily rhythm, not just a special outing, and that even short trips revolve around trying one more dish.

Nightlife

Nightlife seems energetic and late-running rather than sleek or orderly. One recurring note is that the city still feels vibrant at 2 a.m., with people praising the chaos and energy instead of expecting quiet, controlled evenings. The mood appears mixed: lively districts like Kadıköy and Taksim draw crowds, street life, and photos, but the same places can also generate complaints about disorder, harassment, and general intensity. Overall, nightlife reads as social, spontaneous, and very urban, with more emphasis on hanging out, eating, walking, and people-watching than on a single club scene.

London metropolitan area
Food

London’s food scene is broad rather than singular: you can eat very well at almost any budget if you know where to look, but the cheapest options are often chain-heavy or dependent on specific neighborhoods. The city is especially strong in immigrant and regional cuisines, with Indian, Pakistani, Turkish, Chinese, Middle Eastern, West African, Caribbean, Eastern European, and countless other restaurants shaping everyday eating. Markets, bakeries, pubs, lunch counters, and late-night takeaway spots are part of normal life, while the high end is one of the most competitive dining scenes in Europe. The main tradeoff is price—good food is easy to find, but sitting down to eat out regularly can get expensive quickly.

Nightlife

Nightlife is spread across the city and varies a lot by area: some neighborhoods are pub-led and low-key, others are club-heavy, and many people socialize in restaurants, bars, or at home rather than staying out very late. The pub remains central to everyday social life, while live music, queer venues, cocktail bars, and larger clubs give the city a wide range of scenes. Transport shapes the night because last trains, night buses, and taxi costs affect how long people stay out. Compared with some party cities, London can feel more segmented and expensive, but it also offers more choice than most places and can support almost any taste if you know the right district.

Weather vs. what locals say

Istanbul
By the numbers

How locals feel

The weather is described less in statistics and more through atmosphere. Visitors mention cold, cloudy, rainy stretches that do not stop them from enjoying the city, and the Bosphorus and blue water are repeatedly linked to a sense of freshness and relief. Rather than focusing on heat or temperature averages, people describe how weather changes the mood of the city: gray days can feel dramatic, while clear dawns and water views make Istanbul seem bright and alive. The overall sentiment is that the city’s weather is variable, but the scenery often compensates.

London metropolitan area
By the numbers

How locals feel

Officially, London’s weather is not extreme: temperatures are moderate, snow is usually limited, and long heatwaves are less common than in many other capitals. Locals, though, often describe it as dull, damp, and constantly uncertain, with frequent gray skies and enough drizzle to make umbrellas feel permanent. The complaint is usually less about severe rain and more about the mood—weeks can pass with little sun, and winter daylight can make the city feel heavier than the statistics suggest. When the sun does come out, people notice immediately, because it changes the whole rhythm of the city.
