Rafa is a helpful host, he gave me all assistance and convenience since our reservation had been confirmed. The location of his apartment is very good, it takes only 10 minutes to/from Old Street Station. The apartment itself is clean and my wife appreciates the cooking facilities and kitchenware provided.
The streets around Hoxton are good for running (I wanted to know what the Londoners did in early morning and I ran everyday from 06:15 to 07:00 during my stay in Rafa's apartment), so, don't forget to insert your running shoes into your luggage.
