The apartment is very clean and spacious. The area is quiet. The view is amazing, even better than from the public viewpoint nearby. There's a grocery store close to the apartment. It's also very convenient that nearby there's a stop of 23 bus, which goes to the center of the city. The hosts are polite and helpful, solved all the problems really fast.
There were some minor drawbacks as well. There's actually no lockbox and self check-in as stated in listing. And though Christos allowed us to check-in early (thanks for that), he ignored my request to tell us his Wi-Fi password, so when we arrived a bit earlier than expected, we had to wait for him near the entrance door without the Internet to write or call him. There's also a videocamera at the entrance of the apartment, though it's not stated in listing. But these things are not critical, so overall I highly recommend staying at this apartment.
