Lovely hotel for 25th Wedding Anniversary!

Hi there

We are hoping to travel to Bari, Puglia next August for a week's holiday to celebrate our 25th Wedding Anniversary and would like recommendations for a lovely hotel. Our criteria would be centrally located (we do not drive), preferably with a balcony to sit out and have a drink and a pool would be an added bonus also Adults Only if such a hotel exists there. Our budget would be around £200 per night.

Many thanks in advance!
