We stayed only two days at Isabelle's, however this was enough time to note how nice this place is. It's made in a garage close to the main house, it's simple, clean, spacious and cozy. Bed is ok, bathroom is very cute. Garden and roof terrace are available which is a big big plus (for those who can use it, it rained when we were there).
Place is like 10 minutes to the beach by car, neighborhood seems quiet and safe and it's easy to park there.
Isabelle was not at home when we arrived but instructions were perfectly clear to check in. We only saw her few minutes during our stay but she answered mails and questions in a timely manner.
Note that there are not blind curtains so you may wake up too early if being on holidays. Internet connection is really weak, almost inexistent, we had to go outside to get the signal.
