We had a great time in Rochelle's appartment. Communication was really fluid, the self check-in process is really smooth. Only a minor delay in the availability of the flat (3:45pm instead of 3pm).
Location's very practical : walking distance from King's Cross and less than 5min away from buses stops leading to anywhere in Central London and Camden Town.
The only small issue we had during our stay is related to cleanliness : a strong smell originated from the kitchen area on our 2nd day. But by leaving the windows open during the day it didn't bother our nights.
The flat looks exactly like in the pictures, the bed is really comfortable.
Overall would definitely recommend Rochelle's place : a great quality/price !
