We stayed at the Hestia on Romvis 9 during the "heat dome" at the end of July 2023. We were so thankful that the room's air conditioning worked well. We actually had one room for my wife and I and one room for our college age son and daughter. The apartment is very convenient for sight seeing. We were able to walk everywhere we wanted to get to for our 3 days in Athens. We took a taxi from the airport here, but could have taken the metro. (Not sure if Metro had an elevator or just stairs for our bulky suitcases. Taxi was more convenient.) It's about a 10 minute walk from the Syntagma metro. There are a few Gregory's coffee shops nearby with yummy breakfast pastries - plus lots of small restaurants nearby. A stone's throw away is a vegan gelato place that has amazing "ice cream." And all of the main sites are within walking distance. Our luggage got lost for 2 days, and if it was to be delivered here, it would have been a challenge. If we weren't in, the delivery folks would have to call the reservation line who would call housekeeping to unlock the front door. We ended up going back to the Airport (via Metro) to get our luggage ourselves. I'd stay here again. The rooftop "terrace" has lovely views of Athens. Close to shopping, restaurants, and very walkable to the Acropolis, Plaka, etc.
