This really is a tiny house, but it is outfitted well and the space doesn't feel cramped.
Lots of little gadgets and nice touches that make the most of the space and make you feel welcome. There are lots of instructions explaining how to use everything and with useful information. We liked the access arrangement - finding the secret panel gives a touch of adventure to the stay (and Chris's directions were very clear).
The only reason for not giving 5 stars is because the bathroom sink does not have hot water. The electric shower is small but has good pressure and a nice variable temperature range.
The Dog House is located next to a set of traffic lights on a road used by buses and next to a flyover, so there is traffic noise throughout the night, but this isn't overly obtrusive and we didn't really notice it on the 2nd night. Good transport links and an easy walk to the O2 arena.
Chris is a friendly and helpful host and was happy to suggest restaurants.
Overall, we enjoyed our stay and would visit again. It's good value for money and is very well located, especially if you are visiting the O2.
