Silk Fab is a very nice place to be in Athens. The building is modern and secure, and the neighborhood very calm. The place has a nice terrace where you can chill out, and a large living room. The bed is comfy and there's a even bathtub if you fancy a bubble bath.
The host welcomed us for the check in and was very friendly and helpful. She pointed out a wonderful local restaurant right across the street where we had the best Greek salad of our trip. There's also some bars and restaurants nearby and the metro is merely 10min away.
