Alessandro's place is fantastic; it's location is perfect and incredibly close to anywhere you wish to go in London by tube (Pimlico's station is only a 5 minute walk from the flat). The room itself, although smaller than the image shows, is kitted out fantastically, with everything you need and more - the host left us many consumables and also everything we needed to know about the flat and the area in the handbook.
For those who want somewhere central to London, with somewhere comfortable and in a vibrant neighbourhood, then this is perfect for you. Just be wary that it's four flights of stairs to walk up to the room!
