Psiri is vibrant. Great falafel is right around the corner. The entrance to Monastiraki metro station is just steps away. Walking to the Acropolis is easy, walking to the National Archaeological Museum, and Syntagma square is also easy.
This is an easy and relatively comfortable place to stay. I arrived at the apartment after a long flight at 1 AM. Even in my jet lagged condition, getting into the building, finding my key card, and crawling into bed was simple. The clear communication made everything straightforward.
If you are looking for a lively and young part of town, this is the place for you. I've spent some time in the Psiri neighborhood of Athens before, and was prepared for the night life. If you are looking for a quiet part of town, this is not it. For me, the location and the value were most important.
Thank you for a wonderful February get away.
