We stayed in Room 3 for a couple of nights at the end of May 2018. Our room was spacious for just 2 people, we had an extra two beds available had we traveled with our family. Our room had a nice private porch, large walk in shower, and a kitchen area with fridge, range, and plates/cups included. The pool area was nice and quiet. Breakfast was included which is a nice touch!
The hotel is 10-15 minutes away from the airport on Kamari Beach. The street to the beach and restaurants is right around the corner from this hotel. Lots of good restaurant options for lunch, dinner, and drinks. A couple places i recommend Soul by Splash - on the corner and seats available for beach, Alismari down the street.
The bus station is a 5-10 minute walk from Kalya Suites, 3 blocks away. For under 2 euro each way you can get around Santorini and visit the more touristy areas of Oia and Fera. Everything connects to Fera first, if you are moving to other stations from Kamari Beach.
I would recommend the Kamari Beach area for anyone looking to avoid the large crowds of the cities. The restaurants were significantly less crowded and the price differences were eye opening.
