The flat was clean, nice and comfortable, just like it looks in the pics. Thelma wasn't in Athens so we couldnt met her, but she sent us messages to make sure that everything was okay and her husband received us kindly. The apartment is not like super close to the turistic area but it doesn't take long to get there because of the metro station that's near. Also if you rent a car it is possible to park it for free on the street (In which, btw, there's a bakery and a nice cheap restaurant). There's also a small supermarket near. If you're going to Athens I'd definitely recommend you to stay at Thelma's.
