We very much enjoyed our stay at Martin's lovely flat. The flat is well equipped for four people and the location is great. The Barbican area is very nice in itself and it's walking distance from mayor sights like St. Paul's, Millenium Bridge or Shakespeare's Globe. It's also close to two Tube stations, so getting around was very easy. Martin was great to communicate with and even made sure to welcome us in person. He had also already stocked the fridge with some basics, which was great to get us started. (There's a Waitrose next door if you need anything else.) We had a great time and would definitely stay there again!
