We enjoyed our stay in this Airbnb.
Location: The Airbnb is pretty close to the Messaria bus station, which can take you directly to Fira and Perissa Beach. There is a grocery store within a 2-3 minute walk from the Airbnb. If you're going to Santorini and planning on taking the public transportation (bus system), I'd suggest finding housing/a hotel close to Fira, just because almost all buses have to pass through Fira. But that's not to say that it was terribly inconvenient trying to get around the island from this Airbnb.
Facilities & Services: Everything was great for the most part! It felt like we were staying in a hotel since there was someone who came in every morning to change the towels and make the beds, etc. The kitchen was pretty well equipped as well.
Potential Areas of Improvement: There is no hook for the shower head, so you have to hold the shower head with one hand. There is a really bright light inside the room and above the doorway. We also heard the water sprinkler go off every night.
Overall: This Airbnb is great and located in a pretty quiet neighborhood.
