Here are two web sites on Relais Villa L'Olmo. It is helpful to post the web sites when asking for information on rentals or hotels. Members may not be familiar with the rental or hotel but may know about the area.
This is a beautiful place. It was restored within the last few years. The manager, who may also be the owner, is very gracious. The lighting fixtures were designed and created by local crafts people and the fabrics used for the slipcovers were manufactured to their specifications.
This is one of a very few agriturism places that I've found that is a short walk from the center of town. However, it is surrounded on three sides by olive groves and vineyards. The website does not exaggerate its beauty.
