If your intention in Portsmouth is to visit the historic dockyards, this is the place. Clean, spacious and exactly as advertised, it's located only a couple of blocks from the train station, the bus station and the passenger ferry to The Isle of Wight. There are restaurants across the street, and a good grocery store in the same building. Nothing could be more convenient. Everything went exceptionally smoothly, and we have nothing but praise.
We stayed at the Gunwharf Quays for three nights in Portsmouth and had a great time. I highly recommend the apartment. We didn’t have a car, having arrived by train and departed in the early morning by bus. The apartment location was ideal for all modes of transit, and very close to the museums of the Portsmouth Naval base. The apartment was comfortable, very clean and the owner was accommodating. I would of liked to stay longer, two full days was not enough for all there was to do within steps of the apartment. Easily five stars.
