I wanted somewhere away from the usual tourist haunts & was a bit dubious about Marina di Pisa after reading about it being a bit of a run down town but it was perfect - loads of character, a bit shabby in some places but quiet, friendly, close to Pisa with regular buses. It's on the coast so there's handy beaches.
The B&B was lovely, breakfast is served outside on the patio so is not available in winter &, in fact, some days we were squashed under the umbrellas when it was raining whilst haveing breakfast but it wasn't a problem. The owner is very pleasant as is the lady who cleans the rooms & serves breakfast. The rooms all go off the 'patio' area & when we first arrived I wondered if I'd made a mistake in booking but I hadn't. The rooms (we had 2 double bedrooms though I think the others just had 1) were fine, clean, with TV, fridge & bathroom was fine too, not very big but absolutely ok. There were no tea & coffee making facilities in the room but the facilities on the patio were available at all times.
I would certainly go back to stay here again. Oh & the owner has pushbikes that are available free of charge so we cycled a few kms down the road to a secluded beach. The road is flat so was no problem. The 1 litre cartons of wine for 1 euro 30 are quite drinkable too!!
