Dimitris' house has everything you need for your stay in Athens. I was surprised to find even a professional hairdryer with a diffuser! The apartment is in the middle of the city and this makes very easy to walk everywhere. It is near to nice bar, restaurants, tavernas. The location is perfect. Even if the surrounding might scare a bit due to the conditions of the streets, I had no problems staying a week there and walking alone. Exarchia is a unique neighbourhood.
The only sad thing is that the apartment is a bit dark and has no view, but the price is fair.
