Misleading, poor location, loud & switched hotels.
Misleading - We wanted to enjoy staying here but felt very misled by the room's description. We booked the room under the pretense that our room would have a "plunge pool"- which is what the room description clearly stated. Upon arriving and seeing the room there no pool.. but rather a hot tub, which I don't understand how they classify as a "plunge pool" (or why anyone would even use a hot tub in Santorini when its 80+ degrees out). The property is very small too, so there wasn't even a community pool we could resort to using.
Loud - In addition to feeling misled by the pool, we also slept terrible here. The hotel is very close to the main road and was rather loud early in the morning.
Poor location - The location in proximity to everything was also less than ideal. Be prepared to drive 15+ mins or more to do anything.
At the end of the day, we ended up switching hotels and Neptune did nothing for the 3 additional nights we had left there. If we had've had a pool, we probably would have stayed.
If you book something here, just be sure you understand what you're receiving in advance. While we did not feel this resort was "luxury", I do think it was a good value for what was provided comparatively. However, if you're looking for luxury, stay at one of the Andronis locations.
