We stayed in the cave house and it was a great little accomodation, the fact that it was a cave house made it even more charming. reasonably small but has everything you need: bed, sink, shower, toilet, safe, mirrors, storage etc. It also had a lovely little area outside with a table and two chairs which was great for eating breakfast or having a quick relax outside. The accomodation is part of The villas and is tucked away in the far corner which makes it very private which was great. There's also a pool as part of the complex which was great to cool off in and wasn't huge but was a reasonable size given the size of the villa.
The location was great, it's in firostefani which is about 10 minutes walk from the pedestrian streets of Fira although you can reach the main pedestrian streets in firostefani in less than 5 minutes and it's also about 5 minutes from Imerovigli. It was just outside the hustle and bustle of town but within a very reasonable walking distance. It's also about 15 minutes walk to the bus station if you want to explore other parts of the island and Elias was very kind to drop us off there for our bus to the airport and offered to pick us up on arrival but we chose to walk. Elias was also very helpful in telling us how to get around the island and provided us with bus timetables and taxi numbers and anything else he could help with.
Overal it was a great place to stay at a very reasonable price. Everything was easy to get to and the stay was very enjoyable.
I would definitely recommend staying here.
