The studio was exactly as Alessandro described. He was very communicative and includes a welcome folder with information about the place, the neighbourhood and anything else you might have a question about. The place included tea/coffee and snacks, and a bottle of wine -- all of which were very nice touches and definitely appreciated. Also, there are towels, soap and shampoo there as well as a hairdryer and iron, which was also great to have. Lastly, the place was impeccably clean!
The studio is a 10-minute walk from Victoria Station, so extremely handy if you need a base to visit other parts of the city. Though, the neighbourhood itself, while exceptionally safe, is not great for culture, food, sights etc. --it is a rather anonymous sort of place without many restaurants or pubs nearby (and, at least whilst we were there, loads of construction works). Also, it is quite an expensive part of London, but we didn't find that there was much value to match the price-tag. None of those critiques has to do with Alessandro's studio, but if you are looking for a neighbourhood with a little more vibe, value or presence -- it's not here.
My only issue with Alessandro's place was that there was no automatic lock on the studio door and only one set of keys, so unless you are on your own or doing everything with your partner, you'll have to coordinate which is a bit annoying. Though super minor!
