Katerina's place is really one of a kind: a 3 minute walk from the Sepolia metro station. The line takes you to the city center in 15 minutes or less. The neighborhood is quiet with all kinds of supermarkets, cafés, and restaurants in close proximity. The studio itself is very enjoyable even for a long stay (my case). Despite all this, my main positive point would be the host Katerina herself. She was a godsend not only with her advice and all-around assistance but because she is a genuinely good person, the best host I ever had on Airbnb so far.
