Fantastic location. You are a 15 minute walk from most anywhere, and the Covent Gardens area is fun and very safe.
Flat was nice. Loved being able to use the washing machine since we packed light. Very clean, with wifi. The photos are a good representation of what the flat was like. It really had everything you would need. More of a home feeling than a hotel, which was great.
We did have to walk up narrow stairs, which I didn't mind, but if you have any trouble with stairs you may want to consider.
All in all it was a great experience. I would definitely stay here again, and highly recommend it to anyone spending time in London.
