Hi Monica,
I love Formentera it is a small Spanish village it is like going back in time. The children play in the square after school and cycle round the village with not a care in the world. How things used to be in the UK.
We have a two bedroomed two bath apartment opposite a small farm Roy is older then me and I did not want him to have to manage to many stair's we did look round at a couple of town houses, but decided it was not a good idea. So it is a ground floor apartment which we love, but we only stay for 4 to 5 months a year.
I know of a a few couples that have moved to Quesada and they seem to love it there so that might be worth looking at. But I am sure Shaun will tell you all about the area's as has been said he has a lot knowledge.
Well good luck do you have somewhere to stay when you come out? Shaun could probably help you on that as well.
Good Luck anyway hope all goes well.
Pat
