Our communication with Stefanos was great, and the flat was perfect for our needs (we were there for 1 night). He was flexible with our arrival and departure times. The street was very quiet during the night. If you're traveling by metro from the airport, please pay attention to the metro schedule he includes in his email. The metro leaves the airport every 1/2 hour (which we missed by 5 minutes because we didn't pay attention to that little tidbit of information). We would definitely stay here again on future trips to Athens.
