Konstantinos place coulnd't be in a better location, right accross the street from the Acropolis museum and under 15 minutes walk from all main attractions in Plaka, Monastiraki, Syntagma and Kolonaki.
The two bedrooms and 1.5 bath are cozy and comfortable, the space spotless and the communication with Konstantinos was fast and efficient; he was waiting for us with the AC on max, which was greatly appreciated!
The views of the Acropolis from the living room are stunning. I would recommend his place to anyone who is visiting Athens. Also, wifi was fast... I wish we could have stayed and WFH!
