Terrible experience! After my reservation they ask me if they can change my apartment for another one because of some safety problem. I agreed. When we arrived to the apartment we found three dead cockroaches on the floor in hall, then we found another one in apartment. During my phone call to GPM we saw huge alive cockroach. We had to change apartment one more time. The next apartment was in dangerous area of the city. Communication with GPM was terrible. Al of the time they have us waiting for phone calls. “I will call you in 5 minutes “ and then 20 minutes of nothing. I am glad that this situation didn’t ruined our trip do Athens. Definitely not recommending this host.
