Fantastic place to stay. Great scenic and relieving view. Perfect air. Remote from tourist and urban noise, yet very close drive to a village called Kalithies (with several restaurants, bakeries and some grocery shops working till late hours) and 10 more minutes drive to Faliraki with its tourists shops, water park, great beaches and larger shops.
The host, Katie, is amazing, kind, very inviting young person who made our stay amazingly calm yet informative and left us with the feeling of wanting to stay more.
Per our personal view, this was much better than a hotel and personal experience whatever hotel that may be. I can say and compare that as a person who traveled a lot and stayed in various luxury places in United State, Europe and Asia.
Several tips:
1) Staying at Katie's requires a car - which is anyways my sincere advise for Rhodes.
2) Gogle Maps brought us about ~150 meters from the entrance gate, so pay attention to the signs on posts and trees saying "Rhodes Retreat". Or/and contact Katie before arrival.
3) Part of the route is a gravel road, don't be afraid of that - small cars make this road without hustle, no need in an off-road vehicle.
4) Katie was kind enough to prepare us nice breakfast meals for some additional pay, but if you want that too, be in contact with Katie prior to arrival.
5) The place contains refrigerator and all needed kitchen essentials, washing machine, even a drier - we used these.
6) The pool is great! Kids and grown-ups among us liked it very much. Is lit in the night. Very clean.
