We absolutely loved this place. It's a spotlessly clean, quiet, beautifully designed, mod house in the heart of old Athens, within walking distance to everything.
Nine of us (ages 50 to 80) stayed here for a week. It looks better than the pictures in real life. There was not one complaint (well, except we wished for a larger coffee maker, which Nicolas cheerfully said he would buy). Rooms were comfy and clean. Plenty of towels and extra bedding. Kitchen was better equipped than my own home, with absolutely anything you could need, from shot glasses to cheese boards. Wonderful soaps and toiletries provided. Showers had good water pressure. We loved being able to do laundry and hang it outside in the back courtyard. Powerful A/C (except in the separate loft unit, but it was cool enough with a fan). Quiet at night. Cool little entrance courtyard with large table where we spent lots of mornings drinking coffee, and nights, drinking wine.
We felt that we had the best location in Athens, in the charming Anafiotika neighborhood. Google it for the history. We walked everywhere, including one of our party who walks with a cane and another who is a fit 80 year old. Many tavernas within a 2 block radius. Agora and other historic sites within a 5 minute walk. And, of course, the acropolis. Sigh.
Nicolas was the perfect host. Communication was prompt and excellent. He helped with arranging airport taxis for us, which arrived promptly and efficiently. He stocked with kitchen with fresh fruit, soda, beer, cake and all kinds of goodies which was a lovely surprise when we arrived.
Do not hesitate to book this place. You will love it.
