We had a very good time at Yema's place.
It is very well located, with a good tube connection to the centre of London.
The area has a lot of shops, and there's a 24 hours nearby.
The flat is very quiet and we could rest without any problem.
The room had everything we needed.
We could use the kitchen but we missed a table with chairs so we could eat there (instead of standing). And there was no living room.
Another little thing was that the bathroom is very noisy (mostly the pipes), and as the room is next to it, you could hear it very loud.
We think is a good option if you want to spend a few days in London. Definitely, good value for money.
