We stayed for two nights on a London visit. Good things: polite staff, quiet room on 7th floor, clean and tidy, everything worked, excellent shower, aircon ok, car park very useful and reasonable value, only a short walk from West Brompton Underground (one stop to Earls Court), bus stop to West End almost outside, good choice of restaurants at the end of Old Brompton Road (10 mins walk), 24 hr shop nearby, lifts prompt and swift.
Bad things: only one rather thin small towel each., breakfast moderatre and scrambled egg indescribably awful.
We have stayed here before on a number of occasions - the location is fine for us, and parking is a real plus. Breakfast now very moderate - poor ingredients for the cooked buffet and definitely not as good as it used to be.
Conclusion: Good value for money budget hotel - fine if all you need is a clean and tidy room for the night with basic facilities and the location suits you.
