First the positives. This is a pretty stone house, set in a beautiful garden with stunning views of surrounding hills, and several outdoor seating areas, including a shady terrace and seats on the lawn. Kitchen and dining room well equipped, pretty bedrooms with antique furniture, nice views. The pool is a bit of a walk from the house, so remember everything you want to take with you (and the owners like the house and pool kept locked when not occupied, so there is a bit of faff with keys etc), but once there it is lovely, with cushioned wicker pool beds, nice paving, roman steps into the pool, which is large and beautifully maintained.
Giuliana and Mario, who live in an apartment upstairs, were extremely kind and hospitable, presenting us with a bottle of wine and a home-made tiramisu. If you want total privacy this might not be the house for you, as although they have their own entrance they were around occasionally in the garden, but did their best not to be intrusive and to make us feel welcome. As the main house has been their own home at one point, there are some things which are not typical of a rural Tuscan holiday home, including carpets upstairs (never had that before), lots of ornaments and pictures, ample kitchen equipment, and a quite elaborate bathroom.
The main downside was check-in. Knowing we'd already be in Italy from Friday, we tried a few times before departure to arrange check-in as early as possible on the Saturday. As well as helping us, we thought it might help Cristina get us done so she could focus on others arriving later in the day, but we never got a reply. So we rang early on the Satuday; after some difficulty getting a reply she said the earliest available appointment to meet near Lucca was 6pm, which would have meant not getting to the house till 7pm or so. We felt this was unacceptable, and said we would make our own way to the house (which one of us did by using google earth to find it - no directions were given) and Mario kindly met us on arrival. Cristina arrived later; she was obviously trying to do too many check-ins on one day and was just not coping. In an era of satnav it really should not be difficult to give people directions to go directly to the house and if necessary leave a key, and then arrive at leisure to do the passports etc. Indeed, this is what we have experienced the last few years in Italy at other houses. Meeting at a Macdonalds is unnecessary and wastes everyone's time. It was a bad start.
