My husband and I enjoyed a very pleasant stay at 30sqm of wood and stone. Nasir and Nancy were delightful hosts. They were very helpful and communicative, but also went out of their way to ensure our privacy. (They live in the same hoysing/apartment complex.) That isn’t always an easy balance to strike, but they did it well.
While it would certainly have been possible to find more luxurious accommodations in Athens (e.g. a posh 5 star hotel), the space was clean, home-y, centrally located (we were able to walk to the Acropolis in under an hour), and as shown. I think it was very good value for everything provided. After a week of eating out at restaurants, it was also really nice to be able to cook for myself!
I thought the mezzanine bedroom was quite fun. It rather reminded me of an adult take on bunk beds. I think the pictures show the sleeping space as is, but I would simply point out to anyone with mobility impairments (perhaps including thise who wake up super groggy and uncoordinated) that it might be a challenge—particularly given the lack of railing.
All in all, a great Airbnb worthy of consideration. Safe & happy travels! :-)
