Amazing location. You can walk anywhere you need to get in the most happening part of Athens from here. Clean place, quiet building, and the furniture had been upgraded since the photos were taken. Nicholas was super communicative and sent a lot of helpful information ahead of our stay. Solid amenities and pretty comfortable for a larger group to stay affordably. A/C was some of the best we had in Greece. There is a little street noise in the morning because it's in such a busy part of town, so if you plan to sleep late, this may not be the best place for you. It wasn't a problem for us since we wanted to be up by 9am every morning.
One tip: keep an eye on the water collectors below the wall A/C units. We were staying in summer and it was quite hot so we had the A/C on, and one of the jugs overflowed. We caught the others in time, but good to know that you need to look out for that!
