I communicated mostly with Yannis(the other host).
He was an amazing host he gave me precise information about how to get to the apartment, how to get in the building and how to use everything there and even gave me tips, like where to eat breakfast.
The apartment itself was really clean and would be perfectly enough for 2 person. I was alone so it was more then enough.
The biggest advantage for me personally was that since its really in the center you can reach alot of restaurants,bars and sights you want by walk(most places are reachable under 20-25 min walk the hill is 45 min away so thats a little bit longer walk but still manageable) so you can spare spending on transportation.
I had a problem with the panel that lets you in the building because a heavy rain jammed it. I had to leave the apartment to go to a tour but i messaged Yannis(it was around 9pm) and he fixed the problem under 1,5 h.
I highly recommend to book his apartment.
