It was a nice, clean and big apartment, however I found it quite difficult to travel around with the bus at first. Χριοτινα helped me and told me about the different routes I can take but I would still prefer an apartment in the center in hindsight. If you do decide to stay outside the city center, I can recommend the app Moovit.
The check-in was unproblematic, Χριοτινα was very nice and always replied fast.
Perhaps it just takes a bit longer, but i didn’t manage to get hot water to shower.
It took me about 25 minutes to get to the city center and about 30 minutes to get to the airport.
