Rio and his wife were so accommodating. We were taking the train from Kalambaka. The train was suppose to arrive in Athens at 22:12 but we were 30 minutes delayed. Luckily Rio and his wife were very flexible and allowed us to check in late. We arrived to the AirBnB at 23:30 and Rio's wife was very hospitable while checking us in.
NOTE: There are some stairs leading up to the AirBnB location for others to be aware of in case there are some accessibility concerns. In addition, the bed is lofted which require a couple steps to the bed.
The location is 15min from the nearest metro station (Acropoli). We had to catch a ferry to Santorini from Piraeus the next morning. Taking the metro from this location to Piraeus is not as convenient as it will require multiple transfers (two total). Other than that, it is within a 15 min walking distance to most areas or the nearest metro station!
