Massimo is definitely a Superhost! We stayed at Massimos flat for 6 nights and had a great time there. We booked on a short notice and the communication as well as the check-in was very easy and uncomplicated. Massimo personally welcomed us and had some nice tipps already but also sent a very detailed email afterwards with very nice tipps and recommendtaions for the upcomming days - which were all very helpful!
The flat offers everything you need: a cood working aircon, a comfortable bed, blankets, towls, hair-dryer, shampoo/shower-gel, coffee machine, a kettle and also some coffee, tea, cold water and cookies were waiting for us ;) The flat is in a "cool" neighbourhood with lots of bars and great restaurants. It is not a "quiete area" - so people live and are enjoying life here, but we were not bothered at all and had a great time.
Also everything is in nice walking distance - shops, bars, restaurants, the city center, metro stations, bus-lines and also the fantastic Acropolis is only 20min walking distance or 2 metro stations away.
We really enjoyed staying at Massimos place and would definitely book it again if we come back to Athens.
p.s. Be aware of the crocodile!
