We've had very different and beautiful Air-BnB stays before, a hut in the middle of nowhere in North Finland, a cave in the cliffs by the sea in Morocco and so on, but this is our new number one! The owners are artists, and the whole house is an artwork. Angie and Stavros designed and shaped every little detail themselves, and they did that in an extraordinary creative and tasteful way. Besides that, it's very comfortable, equipped with everything one could need. An oasis quite in the center of Athens (we walked to Acropolis, it took us 40 min), with a shady terrace in the garden, another one on the rooftop, comfortable beds, brand-new washing machine, dishwasher, and, as a cutting edge, a clean, chilly pool in the garden, which you will estimate well after a day in summerly Athens. The hosts are extremely warm and helpful and did just everything to make our stay great.
It's worth the trip to Athens itself!
