Nice stay with Simon, but we were quite dissappointed during the arrival as we cannot find the key to enter the appartement in the key lock. It was around 10.30pm when we arrived and no one answered our call atm. Then, other guest opened the door for us but they were in our room ! I thought there were some misunderstanding as Simon said that the room should be empty. For improvement, I think Simon should lock the door of each room so that other guests cannot enter our room before we arrived. Beside that, everything were great and we enjoyed our stay in London !
