Rio's house is simply wonderful. Small, perfectly clean, the space is completely organized and so full of nice details that we felt like home. The position is really good, walking distance from main sites and public transport (10 min to Acropolis, 20 min to Syntagma square). Maybe it's not very bright and the bathroom is a really tiny one but the ambient is so, so, so lovely that anything else doesn't matter at all!! We didn't meet Rio but he always answered our message in a short time; we met his wife, she was really kind and gave us useful advice about the neighborhood and about a (great!!) tavern to eat traditional greek food. What else..We loved it!Hope to come back soon!
