Very good place to stay in Athens. Many shops, GREAAAT bakery, bus stop and very nice promenade near the flat. The connection with the center is also great however I encourage you to check how Zakynthos (the stop next to the flat) is spelled in Greek alphabet. The apartment got everything you need. We've never met Monika but the communication was great via email and her friend Krystyna showed us eveything and even helped us with the first shopping in the supermarket.
