Highly recommended. Roberto and Ágata were very nice and gentle, the room is comfortable and clean, and the house is very well located.
Caledonian tube station has elevators and it takes you straight to Heathrow Airport (you don’t have to carry your luggage up and down inside different tube stations). There also a couple of overground stations very close to the house.
Upper Street, 5-10 min walk from the house, has very good restaurants. Rok Islington was really good (try cabbage salad! Sounds odd but it is great).
