This is a really hard place to rate - the hotel is ok, a little basic, but trying very hard to please. However, the area it is in is abysmal.
We booked it quickly without much research, mostly based on hotels.com rating of 7.4/10, and we arrived about 9pm on a July weekday with two small kids. There were drug dealers operating openly just down the street and about a 100 metres or so from the entrance 20+ homeless people living on stained mattresses under the overpass of Stalingrad tube station. The street was quite rowdy and did not feel safe. Thus, the hotel kept its front door locked and buzzed you in. We had to go out to eat, and walked about 20 mins south to get away from the worst of the area, but halfway through our meal a wild-haired and unwashed man leaned through the open window of the restaurant, naked to the waist and clearly stoned, asking for money. When I said no (I had only cards on me) he turned away and we saw the four open sores on his back, each about 2 inches wide. Not easy to explain to my kids. I have travelled regularly for my work for the last 17 years and have stayed in a wide variety of places, but can't recall ever staying anywhere more rough.
The hotel is trying hard, and is ok - but do not come here in the evening with children. I think the surprisingly high 7.4/10 review comes about because the hotel are trying so hard, and there is no question asked here by hotels.com about the area the hotel is in, hence my middle voting all the way.
