Even tho Ana doesn't speak English very well, not only she managed to get us to her place but she also recommended us what to visit in Athens and the fastest routes to get there.
The building is very central to the main attractions, you can get to the Parthenon area in just a 5 minutes walk.
Our room was really nice, the decorations were very classy.
We had access to the bathroom and kitchen, had amenities just like in a hotel (slippers & bathrobe too).
The place was kept clean and tidy! She was really caring and we didn't notice her around.
Only two things that you might be bothered with is the noise coming from the street which is loud, I suggest you to bring earplugs with you.
Also, it was really hot in the room, there's a ceiling fan but the temperature in Athens right now is 35-37 C / 98 Fahrenheit.
Overall, I would definitely suggest you to stay at Ana's house.
She's a good host and her place is beautiful!
