The best thing about the apartment is the location. It is right in the middle of a great area with lots of shops and places within easy walking distance (a bonus during the transport strike!)
The worst feature is the stairs - which are dark and rickety (but obviously outside the control of the host). Being on the fifth floor, the rooftops views were lovely, but the walk up with suitcases was a struggle. We had four people stay and it was cosy - I think six people would be pretty tight.
The cleaner (who was very friendly) came right on 11.00am so be ready to check out on time!
