My mum and I stayed in Sal's apartment for nearly two weeks while visiting London for a wedding. The apartment included everything we needed for our stay and Sal went out of his way to make sure we had everything we needed (including breakfast supplies). Sal was very responsive to any requests or questions and made sure we were comfortable. Check in was easy, with Sal's shop being downstairs from the apartment and the location was fantastic. It is walking distance to both Old Street and Liverpool Stations and there was a bus stop out the front - making getting around London extremely easy. Our only tip is to bring ear plugs - the street is very busy and noisy, but Sal does mention this in his description of the apartment.
