Our time in Calci was great; Tommaso was very helpful and accomodating, coming to meet us at the airport so that we could follow him back to the accommodation. During our stay, Tomasso was helpful in suggesting places to go, and to eat at, and quick to try to sort out any issues we were having.
The property is behind a gate, and up a steep, narrow, track with a couple of hairpin bends on it. That was quite a challenge for me (wrong side of the car) and our gutless Fiat 500L, but we managed it.
The accommodation was pretty much all that it said on the description; it's quite rustic in its decoration, which fits well, but well equipped. The lounge/kitchen/diner is spacious and as comfortable as you'd expect. All the rooms are a good size and have air-con units fitted (although, as you can see from the description, there's an extra charge of you want to use it). It's very well equipped with bathroom facilities! My wife and I both found that our bed was a very firm, even for me; a mattress topper might've come in useful.
The pool is great and, being unheated, was a blessed relief from the heat. We spent a lot of time round, an in it, and we were very pleased by how clean it was.
Calci is an interesting little town; the monastery museum is well worth a visit and it's easy to get to Pisa and the hypermarket near Pisa.
The highlight of our week was when we came back one night and the lights on the track didn't work; the whole are was lit by fireflies! It was wonderful.
