It's a very nice room if you want to see the city, and you need somewhere to sleep.
It's very small, but you have everything that you need to stay some days. The Bathroom is very nice, also.
The best part about the room is the location.
It's very close to Hyde Park and near Notting Hill, between two metro lines and a bus stop. Even the neighborhood is full with restaurants and shops.
The only problem is that the room is a basement actually. So it smells a little from the humidity. Not a big problem but i don't recommend it if you have issues with your breathing or you can't stand weird smells.
All in all, it's a good deal for the price and the location.
