Dolphin House offers modern apartments well situated close to Pimlico tube station. We had booked a studio apartment for 1 night , price £135. We were upgraded to a one bedroomed apartment, very spacious, comfortable and quiet. The complex is in large old red brick buildings, it has a pretty garden and a nice indoor pool and gym to which residents have free access. It's a nice 15/20 minute stroll along the Thames Millenium walk to Tate Britain. There is a good choice of restaurants in Denbeigh St about a 10 minute walk away. There is a cafe on site though we didn't try it.
