Our stay was excellent. The flat was very clean, all amenities were present including a modern and functional kitchen. We had a small bit of trouble finding the place, but Thomas was easy to reach by phone (and quick to respond via email while booking).
We were a 2 minute walk to the bus stop, and 5 minutes into the centre of Morden, where the underground was located. There were also a few coffee shops and a small market there, so getting what we needed for the flat was a snap.
Definitely recommend, and we are in fact staying with Thomas again on our return trip.
