Been to see a couple
The Seaway was a no-no - it was a very small room in the loft with not very good cooking space (but hey that's only my opinion!)
The Clematis was very nice: nice sized rooms each on suite (which helps)
Another option is Bournecoast (as as been mentioned before) they have a good few studio flats etc but i think you'd be looking at £500 pm for them. (+bills)
Anywyas hope that helps, pm is you want a more detailed description of either!
