Good points: Great location. An easy walk from Euston, as well as an easy walk to theatre land. Plenty of bus or tube alternatives too if you prefer not to walk.
Check in was very easy. Our room was even available three hours early which was unexpected and appreciated.
Great price via Expedia too.
Negative points: the downside of a reduced price room is often that you get the lesser quality rooms. Ours was on the top (7th) floor. The lift only reached the sixth floor.
The room corridor was chilly, as was our room. The central heating radiator was set to Max, but it was only lukewarm at best. Fortunately an electric radiator was also in the room which we were able to make use of. The bathroom was very chilly. We both had showers that were only just warm rather than hot! The second bath towel sourced from the wardrobe had black streaks on it, so my wife refused to use it and used mine instead even though I had already showered with it.
Other than that the room was well prepared and clean.
Overall this is a decent hotel and I am sure the majority of the rooms on lower floors are of an excellent standard, having stayed in one of them in the past.
