I think that Chateau Du Pin offers a great ratio quality/price. In this place you can relax and breath the atmosphere of a warm and magic Bretagne.
This hotel is perfect for a short romantic stay.

We found the beautifully decorated house an absolute treat to stay in (or would have been, entirely, if we hadn't had the kids with us). The rooms were delightful, with paintings made by the owner on the wall and books by the bedside, a great bath and shower. the rest of the house is equally wonderful - though a little delicate for children. The breakfast, too, was not exactly rough and ready (gateaux rather than croissants) but the hosts were affable and more than ready to listen to our french and chat. the lounge, in the evening, with quiet piano on the stereo and stacks of beautiful art books to browse through under those wonderful french reading lamps was exactly what a refined evening should be. i wouldn't really recommend it for young families, however - slightly ancient staircase, having to drive to get all food apart from breakfast, slight case of 'don't break anything' paranoia etc.

After a bit of a search we found the Chateau and was impressed from the word go. The welcome was warm and although we had chosen a particular room in advance, they were more than happy to change it for another if we wanted. We had the run of the house and they were happy for us to select from their CDs and relax in a lovely lounge. The owners are delightful and were happy to sit with us and talk about their art and music that we liked. The room was great although the access to the bathrom was like going through a small tunnel but once through it was worth the effort.
We ate there and the meal, whist a trifle unusual, was fine, they had a selection of wines reasonably priced.
At breakast the owners again came and sat with us and wanted to know about our travels and whether we had enjoyed ourselves.
The house is superb and the owners put as much effort into making their guests comfortable as they have in renovating this beautiful house.
