This is a very nice flat, my friend and I had a really good time here. It's spacious (for 2 people), cosy and you have everything you need. The best thing is the location: Regent's Park is very close by and you can walk from here to a lot of other great sightseeing and shopping spots.
The only criticism I have is that the shower is not really built for tall people and on one day there were noisy neighbours who were apparently partying until 3 a.m. All the other days it was quiet though.
When we arrived we thought that the building doesn't look that nice from the outside, but it didn't bother us as the flat itself is great.
