It was my 5th time in London and it was one of the best hotels I have there.
Close to the tube station, some restaurants & pubs, Nature & Science Museum (5-7 minutes walk).
Bad Italian restaurant in from of the hotel, I can't advice it as a good place. But Grafunkel's is good near the tube station.
Hotel: nice rooms, good bath, standard breakfasts, normal staff. Good one. In case of reasonable price (depends on period) I would go there again.

This hotel is about 5 min walk from Gloucester tube station which is on the picadilly line- this means rather than paying for the Heathrow express, you can catch a standard train that goes to Heathrow ( stopping most stations) for about 2.80 pounds.

It is 5 min walk from large supermarket (Sainsburys) or 2 min walk from smaller supermarket (Waitrose). Laundromat across the road 2 min walk. Lots of fast food near tube stop and a few average restaurants.

Hotel itself is very clean, rooms not a bad size, wifi good, breakfast good, they leave little complimentary gifts most days ( eg bath salts, loofa, candle) which is a nice touch. Also free champagne each night. The staff were not friendly on the whole. They didn't make eye contact to say hello or look up if you needed help. Some staff did not speak English with confidence ( mostly at breakfast) so sometimes it was a bit tricky communicating.

We usually stay around the corner at Base2stay which is in a better location ( in terms of facilities and restaurants near the Earls court tube station). If I am lucky enough to
visit London again I would choose Base2stay first ( it also has basic cooking facilities) but the Ashburn is a good second choice.

Stayed here when we went to watch cirque de soleil walked to the Albert hall took approx 15 mins , it was ideal nice shops in Kensington high street . Room was on top floor 504 quite small we had booked a superior but it was ok for our two night stay, husband found it far to hot . Found a great Thai restaurant on earls court road Addies Thai cafe great food reasonably priced. Breakfast in the hotel was good did not need any extras. Would stay here again on our next visit

I stayed here for 1 night using BA points. The room was clean with high end toiletries, and I loved the amenities (a glass of champagne in the evening and loads of free newspapers). The location can't be beat as it's a few minutes from the Gloucester Road tube, grocery and drug stores, and Hyde Park.
