Instruction of check-in/out was crystal clear, location is very close to central London so good place to stay. The access from subway station to the house is a little bit far, it's about 13min by walk and street is bit dark in night time, but I didn't experience any dangerous scene, so totally it doesn't matter.
House is clean and well maintained, water pressure in bath room was a bit weak but I could take a shower. Thank you for hosting me.
