We had a great stay at London! The flat (and kitchen) is very well equipped, everything quite new. Private bathroom and bed are very comfortable, especially if you like your mattress to be firm (we did). Location is close to the city centre with good connection (tube & buses). We didn't meet Alex or Iliyan in person, but the communication through mail was excellent and check in/out was super easy (there is a concierge service). Fully recommended!
