The house is spacious and light, with lots of living space and the outdoor deck leading to the beautiful garden. I never tired of watching the light play on the two stands of bamboo. The house is full of original art- and craft-work, and we kept finding little extra treasures throughout the week. The kitchen is extremely well-equipped and we managed to have most of our meals outside (in mid-July). Beds were comfortable although the duvets were too hot for us so we ended up sleeping under sheets only.
You can walk into the village on the flat in 15 minutes (although it is not a particularly inspiring walk). There are two baker's shops in the village; we thought the further one had more choice and it does a range of groceries. But we most enjoyed going to the relatively new village co-op shop across the road, which offers a range of local meat, dairy, fruit and vegetables, as well as some standard grocery items, and is completely staffed by local volunteers. There is a new Super U supermarket on the Lorient side of Pont-Scorff (about 10 minutes drive) that has everything else you might need, including fuel.
There is not much to see in Arzano itself, apart from the church (currently being restored) and the donkey sanctuary. However, it is a good base for exploring the area; we went to lots of local towns with historic centres and half-timbered buildings, as well as the world-famous stone alignments at Carnac, all within one hour's drive. The local tourist offices were unfailingly helpful and provided lots of useful information.
The owners responded promptly to any questions before our arrival and were reassuring about the couple of minor problems that cropped up during our stay. You must be reasonably confident in your French, however, as they have absolutely no English.
