We had a very pleasant two night´s stay at Osh´s place, myself and my two teenage daughters. Communication was very good from the start, and service level was top notch. Our suite was located on the first floor, with the window towards the street. A fairly quiet street, save for building work across the road that tended to start a bit early in the morning (but nothing Osh can be blamed for!)
It was a heatwave in London when we were there, and the place has no aircondition, so the first night was somewhat hot. When I the next day asked Osh whether he had a fan available, he kindly went out and bought one for us to put in our room! A service level I have rarely met anywhere else.
The place is newly refurbished, and very central in London. It takes only a few minutes to the tube, and there are a good amount of great restaurants in the local area. You can walk down to Portobello market in a few minutes.
To sum up - all three of us were very happy with our stay, and would highly recommend it to others. Good value for money. The only things that didn´t work terribly well was the TV and wifi, but being a new place I am sure they will iron such wrinkles out easily.
