It was a pleasure meeting Joe and hsi dog Bruno. They are so friendly and love to help with everything. Joe recommended very nice food and party places. Their apartment is just a 2 min foot walk away from the next bus station, from there the access to the city is really easy (ca. 20 min bus ride to Westminster). I'd love to visit them again and recommend their apartment for everyone who'd like to spend some sightseeing days in London. :)
