Imerovigli is, in my opinion, more lovely than Oia. This house is perfectly situated on the stunning caldera footpath and is striking in every way. Host is fantastic communicator, there is daily room service, other-worldly views and sparkling clean. We loved almost everything about it.
Only downsides: the advertised "hot tub" is lukewarm at best and uncomfortable. I asked host to increase temperature, which he declined. In the sister unit next door, the guests were loudly complaining that the "hot tub" felt like wetsuit diving. Secondly, beware if you are a light sleeper. Basically this home is split in half with two private units under the same roof. They were playing music the second night which made it impossible to get to sleep for some of us. I recommend noise cancelling insulation or posting a sign "Absolutely no music allowed."
