Looking at moving to a new flat. My dp prefers Holborn but I prefer Clapham. We are mid 20s
Clapham: I like it because it's more residential, beautiful buildings, has a young vibe, we have friends who live there. The downsides are the rush hour tube to work. The flat we are looking at is a large two bed on a garden square in Clapham Old Town.
Holborn: Walk to work in 10 mins. Super quick to get anywhere in central. Rent is more expensive but about the same price as Clapham Flat + Commuting costs. It's a slightly smaller two bed flat. I find it a bit hard to 'switch off' being so central.
