PROS: This house has an AMAZING view. The balcony and terrace are perfect for watching the sun rises/sunset and large enough for 8+ people to enjoy. By staying here, we did not have to pay top dollar at a restaurant nor fight the crowds to watch the sunset.
The bedrooms & bathrooms are spacious and clean. It's located in downtown Thera so everywhere you want to go is a quick walk. The house is also the start of the hike the Caldera (highly recommend doing!).
Ms. Fay from the TopHouzzing Properties was extremely helpful in getting our group transportation to/from the port and booking a private catamaran for us. She was quick to respond and very detailed.
CONS: there is not a cleaning service or large trash outside to throw away your toilet garbage. The owner said he would come take out the trash each day, but did not. During our 5 day stay the trash was taken out once.
The wifi was very spotty. The owner had trouble with it from the beginning, and during our stay 1-2 people could use it at a time and for very basic needs. We would often go to cafes to get wifi for when we needed a strong connection. If you are planning on using it for working remotely or uploading documents for your flight, it is not reliable.
The toilets continue to run unless you flush them multiple times. The owner warned us about this, telling us that if it keeps running after multiple flushes we need to tell him so it does not drain the whole tank. This was a constant battle at the house.
For a house that holds 8 people there were not enough large drinking glasses for everyone to have a glass of water.
OVERALL: I would stay here again solely for the location and views. I don't believe it to be unreasonably priced and by the end of our stay it felt like a home. If the couple things listed in the cons section were fixed this would have been a 5/5 star rating.
