The house is very lovely, and the terrace has a great view of the water. I highly recommend and would definitely stay here again!
The house has a lot of amenities -- there were an iron, washing machine, drying rack, microwave, oven, hair dryer, etc. Kitchen was well-stocked with cutlery, pots/pans, and dishes. We visited in the beginning of August, and the air conditioning was strong enough to keep us quite cool.
It's about a 5-minute walk to the town center, and 10-15 minute walk to the beach. It's also very close to the bus station, which was helpful.
Salvo was generous enough to drive us to the bus stop after we checked out (although the bus stop is very close, there are quite a few stairs to climb).
There are definitely stairs involved -- to get to the town center side (or to the funicular station), there are stairs up to the main road, and to walk to the beach, it's quite a few stairs down to the beach.
It is about a 10-15 minute walk downhill to the beach -- it's also possible to walk up (definitely a bit of a climb -- we did it once, and I thought it was very manageable, but my partner felt quite a bit tired and had to take breaks), but I'd recommend taking the funicular up to the town center. If you have major mobility issues, the stairs might present a bit of a challenge. But it's possible to take the funicular down to the beach as well, so I wouldn't be too concerned.
