We loved it here. 10/10 for location on a street with cute cafes/bars. And only a short (maximum 10min) walk to stunning locations including Monastiraki Square.
The accommodation was well equipped with kitchen utensils and bathroom essentials. the bed was comfortable, a great shower and AC. With access to a laundry as well I felt like it had everything I could never need.
Romanos and Athena were amazing hosts, very quick and easy to communicate with. Athena was very friendly, gave thorough check-in details and recommended some great local places to eat.
I would only note that if you're a light sleeper to pack some earplugs or white noise. Some of the local traffic and people coming in and out of the building can be heard. This didn't bother us though.
