The apartment is great! It's spacious, clean, has a great view, and has great amenities. We appreciated the clothes washer, along with the laundry basket, clothes pins, and clothes line on the patio. We also appreciated the food and drinks provided in the refrigerator upon our arrival, which included ham, cheese, eggs, bread, milk, butter, fruit juice, and bottled water (you can't drink tap water on Kalymnos), as well as the bowl of fresh fruit on the table. There were nice little extras in case you forgot something, like a plug adapter (in the small basket next to the TV), and sunscreen and bug spray (in the cabinet to the right of the entry door). Shampoo/body wash is provided in the bathroom, along with plenty of towels.
The location is perfect if you are a rock climber, and it is convenient to walk to anywhere in Masouri. After our arrival I sent Popi a message asking if there was any extra toilet paper, and she appeared within 15 minutes with more! I was a little nervous the day before our arrival, as I had to send two messages asking how to find the apartment and how to check in; I guess she must have just missed the first message because she replied quickly to the second one, and replied quickly to any other messages I sent during our stay.
The mattresses were not great, which is common in Greece. It didn't bother me, but my husband has back problems and he said it wasn't supportive enough and made his back hurt; he slept on the couch the last 2 nights instead.
A couple things to note:
-The directions given to us for finding the apartment were not very specific, and there aren't really street names or addresses in Masouri. If you search for "Sdregas Flats" in Masouri on Google Maps, you will find the exact location. It is on the northern end of the "upper road" (which is to the east when looking at map), at the last sharp bend before the upper road meets up with the lower road. The "lower road" is the main one that goes through town, and it's a one-way road (heading south) during the summer, so the upper road is used to go north from Myrties to Armeos.
-It is a steep climb up the hill if you take the steps from the center of Masouri to get to the road with the apartment. Walking up the road from the direction of Armeos is easier, especially if you have bags and did not get a taxi to bring you directly to the apartment.
