This location is brilliant, very close to the center and the shops/bars/restaurants but there are a lot of steps, which was fine for us but be warned it's a hard climb! Maria arranged for our bags to be carried down to the cave and back up when we left which was very nice.
The roof terrace (which is just above the apartment) is the real selling point for this place, the view is wonderful. We sat on the chairs there all night with a bottle of wine and even picked up some food nearby and took it back to sit there and eat it. It's just beautiful.
The inside is pretty basic but has what you need and it's very spacious. Nice and private too!
