We had a great stay in Athens! The house is very spacious, which was great for us as we had two families so one stayed downstairs on the main level and we stayed upstairs. Lots of sitting areas and some outdoor space. The area is super close to the underground station or an uber for about 5 Euro takes you right into the city centre. You could also walk, but we had young kids and it was very hot.
The area itself is not touristy (which is a benefit for us), we had one of the best meals of our trip around the corner. Lots of local restaurants, bars, cafes etc. It's clearly a changing neighbourhood, our driver told us years ago it wasn't safe but now some of the best restaurants in the city are popping up.
I do agree with some of the other comments about the house needing a bit of a refresh. But overall it didn't really bother us and we had a great stay and would recommend.
