The location for us was just right. As dog owners the apartment suited us as the dog friendly beach was just opposite the apartment, and Southbourne itself was walkable in ten mins.
We had everything we needed in the apartment however a couple of disappointments were my wife had to thoroughly clean the microwave before using as there was food left splattered all over the inside from previous usage, plus there was also a pan very dirty with remnants of food left in it, we left that and didn't use it. The lounge windowsill was in need of a coat of paint and a little filler, plus the TV was in the bedroom, although to be fair the owner di offer to move that to the lounge on the third day of our stay. Overall I'd have no hesitation staying here again if we were down this way in the future, but the little touches I've mentioned would have encouraged me to rate it higher, in particular the state of the microwave. The apartment overall was clean, but I'd rate it as Okay.
