Me with my husband and infant son stayed at Marouan's place for 2 nights. The place is located in a very convenient location close to a Metro station. All main attractions (Acropolis, acroplois musuem, Plaka) are within 1 km so you can easily walk. It was easy to reach the location from airport with local transport (you need to change at 1 stop though in metro). For port, we took uber and it was very convenient.
The house is very tastefully done with all amenities and fully equipped kitchen. It also has a nice balcony where you can enjoy your meals.
Marouan was very responsive at all times. He even waited for us late in night to check in. Will definitely recommend to stay with Marouan.
