I would not hesitate to recommend friends and family to stay at Margherita's place in Artermonas. The apartment is a pretty, comfortable and immaculately kept place to stay. It is lovely inside and spotlessly clean, and also includes use of the very picturesque private garden, which is bathed in sunshine for most of the day. Margherita's lovely and friendly auntie - Maria, met me on arrival to show me around and let me in, and was nearby in the next door cottage to assist with any questions. She was so friendly during the stay, that one was left with a feeling of being part of the family rather than just a paying guest.
The location is a stunningly pretty traditional village with excellent bus / car access for exploring the rest of the island. Buses to most locations across the whole island are on an hourly basis. The village also has plenty of good taverna's and restaurants, as well as shops, churches and art galleries to explore.
The apartment is just a two to three minute walk from the main square in the village. Because cars aren't allowed further than the square (which has plenty of parking), it is really peaceful at night time here.
I would certainly come back again.
