Costantino's apartment was very comfortable, in a safe and strategically located area directly connected to the airport via tube, 1 minute away from the house, which made my arrival and departure hassle free. The area is full of nice restaurants, bars and clubs: it was very nice after a long day of walking not having to move too far for some entertainment. The area is particularly desirable for young tourists as it is in a student neighbor. It was very convenient getting out of one of the clubs late at night knowing that my cosy bed was only a 3 minutes walk away.
The flat is comfortable, very clean and exactly as depicted in the pictures with all necessary supplies including toiletries. The place is small but perfectly suitable for a single traveller or a couple.
Costantino could not meet me in person, however arranged my arrival and stayed in touch throughout making any possible effort to accommodate my requests including being really flexible with late check in and check out. On my last day he even allowed me to leave my suitcase in the apartment longer after check out so I could make the most of my last hours in Athens.
Amazing value for money, I definitely recommend.
