Joseph and his wife are adorable and their place matches them in aesthetic. The only thing I can say is that the place is a littleeeeee bit far from central London, located in Zone 2. No nearby cafe's or restaurants. The apartment is in a brand new building with a concierge. Safety is definitely not an issue here. Joseph and his wife were also nice enough to leave us food for our weekend stay. The apartment is also about a 70 pound uber ride to and from all airports. Overall a great stay and my friends and I were very happy.
P.S. The view from the apartment is beautiful!!!
