This is the best rent flat I've ever been to, really! The apartment had literally everything we might need and even more - for example we found a frozen pizza in the fridge, and a coffee machine with full supply. Rooms were perfectly clean and neat, there are two balconies - one with a beautiful view on the city is a nice place to have a glass of wine in the evening (and we also found some wine in the fridge!!)
Surronding is a bit trashy but there's a metro station, train station and a huge supermarket within 5 minutes walk.
Panagiotis was extremely friendly and helpful and provided us with any guidance.
All in all, I'd say it's a perfect place to stay for 6 people :)
