This property was an excellent choice for us - very close to family, with a large room and a comfortable bed (what I would call a queen size bed - larger than a standard double). The ensuite bathroom is small, but perfectly adequate. The apartment is very clean and tidy, although the shower could do with a little mould killing (but it was minor).
Richard was a great host - made arrival/departure very easy, and was happy to let us use the kitchen, washing machine etc. We didn't see much of him as he left for work very early. When around, he's happy to give advice on places to eat etc.
The TV and WIFI internet access both worked well.
The only negative is that, like so many London properties, you are affected by the noise of the neighbours, particularly upstairs, who are not at all considerate. There is very little sound proofing between floors and the bed is on the wall adjoining the hallway. Similarly, within the apartment, there isn't soundproofing between walls and the floors creak. Richard is very considerate and quiet, but he does get up early! And I was always concerned we'd wake him using the bathroom at night. As I said, this is no different to almost every multi-resident building in London.
