We were in two apartments from homm in athens, both were very nice and clean and cozy. The check-in was super easy.
There was just one thing which kind of left a bitter taste: We asked homm whether they could organize us a taxi from our apartement to the port to catch our ferry. They said they could but we needed to pay 50 euros in cash to the driver. As this was way more than we expected, we declined and instead ordered an Uber which cost us only 11 euros at the end.
Still, we would recommend this apartement.
