I stayed here for three nights in August 2018 and would recommend it to anyone!
PRIOR TO ARRIVAL - The host was very responsive to my messages, always within 24 hours. They even worked with me to schedule two separate pick ups (I was arriving via the port and my friends via the airport). While there was a fee for the pick ups this was very much appreciated as it is not easy to find taxis on the spot on Santorini at this time of year. At both arrivals, there was someone there with my name on a sign and the process was very easy.
ARRIVAL - The space was very clean upon arrival and the host did a great job explaining to me all the details I needed to know (how to lock the doors, air conditioning, etc.). They made sure to let me know I could contact them at any time with questions or problems (we didn't have any!)
STAY - Our stay here was extremely enjoyable. There is a maid that comes daily and makes the bed, folds towels, etc. This was an added bonus as it felt like a hotel. The air conditioning worked well and the shower got hot water. We particularly enjoyed the two outdoor spaces available at the property. One is a shared rooftop which was great to watch the sunset and the other is a private back patio area with cool lounge chairs that was fun to sit out at for a nightcap.
LOCATION - The property was in an excellent location - very close to town (less than 10 minute walk) and also very close to the bus station (also less than 10 minute walk). As three girls we always felt extremely safe in the area. My only caveat is that there are some steep hills nearby so I would not recommend this for people with difficultly walking however the same is true for most of Greece.
I have friends looking to go to Santorini later in the year and have already sent them the link to this property as I would recommend it to anyone!
