The apartment is very convenient and comfortable. The kitchen is small but the other rooms have lots of space. The toilet and the shower were clean and in good condition. The weather wasn't too hot at the time of our visit so we don't know how well the air condition works. Mai was very kind and helpful and she answered our messages quickly. There was no problems during our stay. However, if you book this apartment, you must prepare to use the underground a lot, since it's pretty far away from the center (Dollis Hill station is nearby, connecting to the jubilee line).
