We stayed five nights here and found the location very convenient with South Kensington Metro so close. We had a deluxe room which was at the back of the hotel and rather compact. However, the bed was one of the most comfortable we have slept in - and the request for sheets and blanket rather than a duvet was noted and the bed properly made on our arrival. Amenities were top quality and the complimentary soft drinks and tea and coffee (french press) were a welcome touch.
Apero, the restaurant downstairs, was a great surprise. Food and service are excellent and value good for London.
There is a little gym - nice to see as gyms are not common in London.
Service was pretty good - and the staff pleasant. Some technical problems with the room key cards on the first day but that was resolved pretty quickly.
We also found a self-service laundromat about 200m west along Harrington Road that was welcome after 3 weeks travel.
I would recommend the hotel - it is charming and a nice staff and good restaurant downstairs.
