I think Ada's place is fantastic. Me and my husband spent 11 nights there and even though we never met Ada, she answered to our requests immediately. She gave me instructions where I will find the key and helped me used the best public transport to get to her place from the airport. We immediately felt the place like home and we could find everything we needed in it. The only drawback is that there are two flights of stairs to the apartment and no lift. Beside that I will recommend this place to anyone cause I will definitely go there if I will visit London again.
