Lina's room is large, comfortable and it was nice and clean. I was there in late June when it was very hot outside, but the room kept at a good temperature day and night.
I came to London from Germany, to visit a friend in Northolt. Lina's place in South Harrow is within walking distance of him. It is also nicely connected both to Heathrow airport (24h bus service) and to the City of London via the tube.
I did not get to meet Lina, as she does not live at the place. She had prepared the room though, so I had everything I needed. I got the keys to the room via a key safe. I had not used such a system before, but it worked fine.
I recommend this place.
