We were only in Rethymno for one night so our experience is limited.
The room (or studio flat) is on the ground floor and has very pretty stone walls.
Unfortunately it is very damp and rather cold at night (stayed October 5th), but also very very noisy from the road so bring ear plugs!
We weren't too happy when we found out there was no proper blanket, only bed spread, and that the top sheet, once unfolded, was too small for the bed which means either one of us was to go without or we were both going to get cold feet!
Overall an ok experience for the price, I would only recommend staying here for 1 night and making sure you have earplugs and a thick sweater to wear at night.
Also we were told check out was at 12.00, at 11.35 the host was knocking on the door. She was happy to wait until 12.00, but it makes you feel slightly unwelcome!
