We've had a great stay at David and Wenfang's place. The rooms were clean and check in was nice and easy. We extended our stay here due to the great location and how easy it was to get into the city from here. Communication was great too, if we ever had any questions they never left us waiting for a reply.
We do have a few niggles though - we were disturbed at 9pm one night by David and requested to allow future guests to view the room. I could probably have said no but with the other guests stood waiting I felt I had to let them in.
The room is also close to the kitchen so when guests use the kitchen at 4 and 6am like they did when we were there you'll likely be woken up. This is no fault of David's but we felt it should be mentioned.
Overall we had a great stay here and would definitely book it again if we're in the area.
