We enjoyed our stay at Giovannis apartment! The location couldn't have been better. The apartment is 30m away from Oxford Street, next to many good restaurants at the Charlotte Street and you can walk to most of the sightseeing-atractions (Soho, Picadilly Circus, Regent Street..).
Even though the apartment is located in the heart of London, it was calm inside and a great place to relax.
The apartment was very clean. The kitchen was well equipped with basics, maybe a coffe machine would have been a plus.
The only thing we did not enjoy was the wifi-connection. We were not able to check anything on the internet (like where to eat, what to do in London etc.). When our flight home was cancelled we had no possibility to get any information.. We talked to Giovanni about the problem, but they couldn't do anything the time we were there.
One last thing that I would like to mention were the stairs. If you are not in a good shape (problems to walk etc.) or you have to carry heavy bags, you won't like the endless steep stairs. (there is no lift) But if you're in a good shape, you can just see it as a hard workout ;)
All in all, we would recommend Giovannis apartment due to the great location and beacause it's a spacious & clean apartment.
