Flat was nice, clean, hosts were communicative, but we were there in february, nights were cold, and in flat we had only max. 17-18 degrees, and in the night just 15 degrees, we were freezing inside, and it was not possible to set up heating, host said it is on 21 degree, but it was not working, but they brought us external heater, but anyway it was cold inside.
Area where is flat situated I don´t recommend, because in Omonoia Square is heaven for thieves, they stole my phone even I was so careful, but also people who live there told us is the worst area, during the day we saw some people using drugs.
