My husband and I just stayed 4 nights in Oia in Rena's cave house.
we didn't meet Rena until checking out however she was fantastic and always responded almost instantly to my messages. Rena was so kind to assist in arranging our transfers to and from Santorini and I am so grateful for her help.
on arriving to the cave house we were assisted by Rena's porter and cleaner.
the lovely lady who came each day to clean, change towels and make the bed is just lovely and amazing.
the little touches Rena provides for her quests makes the stay so worth while. The cake is amazing.
The walk up to the main street will keep you fit but its worth it.
We also ventured down to the water but this path is not exactly safe due to rocks constantly falling so dont try it unless you are willing to take it slow and be safe as it's also overgrown - this is not Rena's fault etc as it's a public path etc. it took us 40mins to walk down but 15mins to get back up.
overall I enjoyed my time and woyld recommend Rena's property to anyone.
