The flat is very nice and you get exactly what is on the pictures. The communication is easy. You have to have internet on your phone for check in, which might be an important “ahead” information for non EU citizens. The wifi worked well. We walked everywhere and there are lockers at the Syntagma square if you need to store your luggage on the last day. Around the corner is a great bar where you meet locals (not the bar downstairs in the same street). For two people the flat was perfect, with more I would not have minded as we barely spent time in the flat and doors can be closed. Can absolutely recommend the place.
