The Maria's apartment was a perfect stop in Athens for my family. We stayed only for one night, arriving late from the airport and leaving early for the ferry boat to Paros. Nevertheless I think it would be a perfect stay for some days, if you want to visit Athens. The key locker was perfect for a self-check-in, the rooms and the bathroom were perfect for 4 persons. Also parking the car very near the apartment was easy. The neighborhood offer many cafes and restaurants, if you need them. I would recommend Maria's house for sure.
