Anyway, under giving circumstances I booked while we were about to take off to Athens, a 2 hour flight at 21:30h.
At first the girls didn't liked the appartement, since there was no privacy and it's quite small, and arriving after midnight didn't help in a neighborhood which doesn't looked welcoming, and scary at night!
But in the morning it's okay, and if you arrive before midnight and coming from Victoria Park it's okay, as till late there are people in the park. There is even a bakery open 24/7 I was told. There are, small shops, supermarkets, farmacies, bars and restaurants around the park, quite cheap, affordable.
We used the appartement only to sleep, so it was okay in the end. Had almost everything we needed, and Chris was quite helpful and understanding, of our situation: At first the girls wanted to leave (i.e. no airco, privacy, small, etc.), but they gave it a try and liked it at the end. Chris offered to refund our payment for the days not used, which was kind of him.
He also brought us an extra ventilator, towels, etc. Outstanding!
Thank you again Chris!
