Had a great stay in the studio in Pimlico. The studio looks exactly like in the pictures and is very nice and clean.
There are just what you need in the cupboards for a short stay - cereal, coffee, tea, snacks etc.
To sum up: the stay was as comfortable as if you were staying in a hotel.
The area is also very nice. Quiet when you need it and with a lot of interesting bars and restaurants very close by.
