We have had a wonderful time staying in Efthimis's apt. He left us bottled water, traditional Greek cookies, and Fix beers to enjoy. The apt is very clean, well equipped, and the kitchen is well stocked with all kind of spices for a gourmet cook. The location is perfect, close to two metro stations (Thisso and Monastiraki). The apt is walkable to all the attractions in the €30 combo ticket, and the Central Market. We feel very safe walking back to the apt at night time. The temporary down side now for the apt is the construction opposite. The workers started at 7am, and woke up the light sleepers, like my husband. However, with the shutters down, and the balcony door closed, it is not that noticeable.
Efthimis is a perfect host. We were able to get hold of him all the time, even to find out where to buy a light dimmer. He was our concierge in Athens. Many thanks to him to make our stay in Athens a super experience.
