We stayed in Kalypso Houses (Elia) early this month while on 8 days' Greece vacation. We had a wonderful stay there and in fact, at the end of 3 days of stay, we all were wishing we had planned another couple of days' stay more in this property.
The house is superb, exactly as depicted in the photos, nice & cozy and offers a wonderful view of the sea. The swimming pool is nice & clean and the premise is very well maintained. House was very clean and hygienic (cleaned daily).
Maria is a wonderful host - I bothered her with lots of questions before booking the house- she painstakingly answered all my queries in detail and very promptly.
Mirto (the manager) is a wonderful lady - she not only ensured that we had a great stay, she even helped tie up quad bike rental, answered all our queries on going around the place - she was just a phone call away. A big thanks to both Maria and Mirto for being lovely hosts .
The location of the property is its USP - hardly 50 mtrs to the Monolithos beach (this beach is fairly empty and serene and very clean - very good for sunbathing/swimming or even lazing around in the evening) and barely 100 mtrs to the amazing Taverna (Galini) - they serve amazing food particularly moussaka and fresh fish. The Mini Market is also barely 100 mtrs away. In a nutshell, there is no way you will not fall in love with this place.

For us, if we return to Santorini - choosing a place to stay will be a no brainer - Kalypso Houses is the only place to look for. Try this place and you can thank me later :)
