Just wanted to give a quick review of the Southampton Harbor Hotel, which we are staying at for three nights before a cruise. We have really enjoyed this hotel. Very comfortable room with heating and air conditioning that works well. There is a pool and hot tub on site. A small decanter of gin is provided.
The restaurant and bar on the top (6th) floor provides lovely views over the Solent and we have enjoyed seeing ships arriving and departing. The hotel is adjacent to a marina which is pleasant to look at and walk around.
Staff are very service oriented and helpful. There is a free shuttle to cruise terminals, but there is limited space, so sign up early. If you can't use that then there is taxi and Uber service, which are not too expensive.
There is shopping and restaurants nearby (including a Tesco Express), but this is not within walking distance of downtown. The cost is also higher than other options.
