I stayed one week at the apartment.
Location: perfect!
Building: very good, friendly doorman.
Apartment: ok, but not outstanding. Main issue: the bed in the main room is broken, literally. It is very uncomfortable to use in one side. Other issues: Francesco didn't answer mails. Antoanetta did, however. She was very helpful, although it was not her job to do so. Last one: major work in appartment next door causing very strong noise after 9am and during the day. Other than that, we had a great time in London.
