Me and my girlfriend stayed over at Lefteris apartment (#1) in Heraklion for one night.
Lefteris is a very friendly, helpful, and courteous person. He supported all our requests and replied quickly. I can really recommend him as host.
The flat itself has some hickups which should be mentioned.
First of all, the flat is right next to a school and the schoolyard which will lead to loud noises during the day/the morning.
Other than that, the location is acceptable and within a walk of 15 minutes you can reach the city center.
Second, the flat is in the basement which on the one hand is upleasant due to the missing view and limited daylight but also on the other hand due to the typical basement smell and moisture. The whole flat and cabinets felt wet so we did not left our stuff in the cabinets. Using the well working A/C, the smell can be fought.
Last but not least, the flat is very small and the interior is of simple quality. Especially the bathroom was very small and for a normal sized person (male, 185cm, 85 kg) even the shower was hard to use due to the small space and the shower curtain. We did not use the kitchen but we can confirm that all necessary equipment is available.
All in all, the flat was functional for one night and Leftis was a really nice host with helpful hints and a warm manner.
