Me and my friend had a grat stay at Carlotta's. We didn't get to meet her but her mother was kindly welcoming us when we arrived. All our questions were answered quickly by text messages. Carlotta's house is very clean; it has a working heater in the bedroom and enough hot water in the shower so I can highly recommend it. The only thing is that there isn't really a place to keep your luggage the day you depart if there are new guests coming in. After a search we found the nearest Left Luggage point at Liverpool St station.
