I had pleasant stay at Alessandro's place. It's about 7 minutes from subway Pimlico station and 15 minutes to Victoria Station, national railway. Very convenient to travel to everywhere in London and also to the outer cities. I could easily find ways to get there from Heathrow Airport and have no trouble getting in the room without seeing him, thanks to his appropriate instruction.
There were a hair drier and a conversion adapter in the room which was not on the list which were very helpful.
I stayed 6 nights but there was no linen or towel change which was bit unfortunate for me. At the same time I felt easy to find out no one enters the room while I am away.
He, and the other person who took care of the room were also very kind and helpful. They offered to keep my luggage even after I checked out. Overall I am very satisfied with the place and service.
