We stayed at Greg's place for two weeks and it was absolutely wonderful. The apartment is just as shown in the pictures – clean and spacious. The location is perfect – peaceful, beautiful, a stone's throw from Hyde Park and extremely close to Paddington Station. There are lots of pubs and restaurants nearby, and the supermarkets aren't far either. The kitchen was well stocked and we found it quite convenient to cook in there. Greg himself was very responsive throughout our stay, we had no problems with checking in or checking out either.
We loved coming back to the apartment at the end of each day – it felt just like home. :)
Highly recommended!
