Excellent hotel. Highly recommend for any couples who want to relax in a cozy place. There's very nice air conditioning, wonderful staff, and the room was very good, with an excellent breakfast every single day.
We have requested prior to booking that the room be deep cleaned, as the hotel allows smoking at the rooms. They've done an excellent job and we have not noticed any foul smell. Our room was honestly more than what we wanted, and it was excellent.
The view of the city from our floor was also very nice, and we enjoyed the landscape.
Only gripe I have is that not all the staff understand English to the fullest extent, which can lead to some awkward interactions and miscommunications. While not a big deal for the most part, try speaking clearly and with separated words for the best experience (in English).
Location is excellent and a 6 minute walk from the metro station. Only issue I personally had is that in Athens pedestrians are not the priority, so exercise caution crossing the road to the metro.
