Alessandro's place is really well-located! We visited during christmas period when all the public transport is not operating but we still manage to do a walk around london's iconic landmarks. There were snacks and drinks for us at checkin, it was really awesome!
At checkout, he even offered to store our luggages. Great service!
The only downside is that the apartment is on the top floor and the climb is really tiring if you have large luggages. But thankfully we travelled light. :D
