Why should you choose to stay longer than one or two nights
The nicest and larger properties in the area do not accept just one night, unless your reservation is close to arrival date.
And it is totally not advisable to change location every day. You would spend all your time in checking in and out, dragging baggages from one place to the other, going up and down of often crowded trains, waiting for check-in times: check-out is at 10:00 and check-in at 15:00.
We definitely suggest to rent a place for a longer stay and then do your visit from there.
The 5 villages are just 5 minutes ride one from the other so no trouble in reaching them without bags by train or by boat or even walking.
You would enjoy the area much more! Trust a local!
