Mark's appartment is a small house in the backyard of his house. It has a fully equipped kitchen, a bathroom and a cozy and confortable big bed. Everything is new and very clean. He and his mother are very kind and respectful, they even left us some candies. We stayed there 3 nigths and really enjoyed London, only thing to note is that it took us around 30 min to reach the places we wanted to visit. From his house to the underground we had to walk some minutes. However, we think the quality of our stay compensates this.
