I stayed at the Dolphin hotel for two weeks in January 2013 and booked the hotel directly through the Dolphin hotel website (http://www.dolphinhotel.co.uk/) there also listed on a number of hotel booking sites like booking.com etc.
I booked a single room which cost £45 (week night) and £69 (weekends). The room had a single bed, own bathroom and a small LCD TV. My room was located on the third floor facing the park so the noise was minimal but I’m sure the train lines would be a little louder on the first and second floors.
There’s an Indian restaurant close by which I visited and there’s lots of other places to choose from in the area.
Overall a good hotel close to Paddington station and very affordable in the heart of London.
Staff: Were friendly and helpful, pointed out the good spots to eat and things to visit.
Room: Small room with single bed, LCD TV on the wall and own bathroom. *A refundable deposit of £10 needs to be paid for the tv remote*

Rating: 3.5 out of 5 (great location and very affordable)
