I would not recommend Nab's place for Airbnb. I would say it wasn't in the most affluent place in London and is around 15-20 minute walk from the closest subway station. That being said, there were a couple of things that didn't go that well for us.

The room number wasn't that intuitive to find. The taxis that dropped us off, always did so on the side of the building. The building's room number didn't seem to follow any logical sequence of numbers. We had to hunt down the room number on each building. It's worth mentioning that Google maps does not help with finding your room number. His instructions, which seemed clear at the time we read it online, wasn't so straight-forward when actually there in person.

About 1 hour later, after trying a number of stair cases and meticulously looking with no definite logical sequence, we were able to find our room. It was time to take a shower. After couple minutes of fiddling around with the shower knobs, it seemed quite apparent that there was only one temperature setting -- scolding hot. You could not turn up the cold water to bring it to cooler temperatures. This essentially ruined our trip in London. Any sweat we built up over the course of the day, made us think about the painful experience (again) of taking scolding hot showers to clean up.

If you manage to find out how the toilet button works, be warned that the toilet can be clogged easily. As you can see, we did not look forward to coming back to our room after a long day out.

We didn't mind the very limited space, but people should keep in mind that his pictures shows it with the bed flipped up (on the right corner of the pic). Once you bring the bed down (without worrying about breaking the hinges), the place is very tiny. Just something to keep in mind if space is a consideration.

We tried to get in contact with him during our trip in London, but he was 'away' and couldn't help us out. It would have been nice to have the actual owner or renter around to help service problems with the room.
