We stayed for 7 days. The apartment matched all of our expectations. It was very well located, near the subway station, several restaurants, in front of a bakery, 10-15 minutes on foot from the Akropoli. We felt safe in returning at 1:00am to the apartment. The bed is very confortable, it has a good bathtub (and the water is very warm) and the kitchen has all that one needs to do basic stuff.
The host, Thomas, always answered quickly and gave nice instructions regarding our corcerns on safety and mobility.
We would like to give a special mention to Kostas, the taxi driver that Thomas recommended us. We hired his services for 3 day trips and it was great. During the trip to Mycenae, Epidauros and Naupflio (from 10am to almost 10pm on a Sunday) he stopped at a local wine producer so that we could taste the true Nemean Wine. We didn't hire him as guide, so he didn't enter in the archeological sites with us, but the conversation during the trip between the locations was great, especially regarding the current daily life in Greece. He was punctual every time and his car was very confortable.
