Our stay at Sofia and Anna's was great. Their place is perfectly situated ,a 15 minute walk to the acropolis, 5 minutes from the subway and right near a grocery store and plenty of great restaurants.
The check in was great, and they let us stay a bit pass the check out time, which was super convenient as our flight was later in the afternoon and we were able to go directly to the airport after our check out.
The place is very clean, has everything you need (including a little kitchen), linens, soaps, etc.
Thanks for having us!
