Nice and very clean appartment, perfect for a couple days if you simply need a place for the night. Biagio and his cats are great hosts, nothing at all to complain about!
Kilburn may not be the most attractive area of London, but I felt save all the time and met some nice locals during my stay. 2 tube stations (Jubilee / Bakerloo) are in walking distance, as well as several bus stops, so in 30 minutes you get to the City Center, Camden or Wembley Stadium.
The sofa bed sure is good enough for a couple nights. All in all, you get a nice room for a really good price, I would absolutely book again!
