Pros:
The communication with Nikitas was super fast. He is a great host who cares about his guests, very helpful, he shared some tips with me and was able to answer all my questions.
The kitchen stove was brand new and he even bought quickly the right pots that work with these kind of induction stoves (because the other pots were incompatible) for me to be able to cook dinner.
The location is very good. Residential neighborhood, very quiet and family oriented.
Good connection by several buses to the city's main attractions and points (like Omonia, Syntagma, etc.) - 15 min to the nearest metro station.
