Southampton was very short of hotel rooms due to the cruise ship season. There was also the boat show on. Crescent Place is exactly what it says on the tin. It's no frills students halls of residence. The room was ok, small with even smaller ensuite bathroom. Remember to bring you own toiletries such as shampoo and soap as these are not available in the rooms. No tea making facilities, however if you bring you own, you can use the kettle in the common kitchen.
Walls were a little thin so students being students, you can expect a little noise.
If you need a place to put your head down and expect a reasonably cheap rate then this is ok.
