Matt and Ubie's place is quiet and spacious. We enjoyed our 2 week stay there for our London family holiday.
Matt is very responsive to enquiries and we were able to quickly and reasonably resolve some minor issues.
I would probably not recommended it if you have young children though as the local train station has a lot of steps and the alternative options take a lot longer to get into the city.
Without children, this place is perfect for 2 couples, particularly as both bedrooms are on opposite sides of the house.
