The Superior Apartment is very large giving families a lot of space to spread-out. We confirmed check-in time the day before, but we did have to wait about 15 minutes for Alex to arrive. Fortunately, the housekeeping staff were just leaving, so they called him for us. I was a bit apprehensive if he was going to show; once he did, it was smooth sailing.
Being there for just two nights, we did not use much of the facilities. There are 2.5 bathrooms (1 has a huge shower, the other has a corner shower with hand-held shower head you can mount). The facilities were extremely clean and there were plenty of high-end towels. The only issue we had was the lack of hot water... there must be some switch you have to turn on, but we were not made aware of it.
The bedrooms are large and quiet (even though they overlook a very busy street). The beds are very comfortable and are fitted with nice linens. There is a safe in each room along with good closet space. All bedrooms had a TV.
The living room is a great size, comfortable sofas, and access to large TV with Netflix. Check-out was simple (we tidied up, put the keys on the dining room table, and shut the door). Getting to/from the 2nd floor apartment and the street was OK with elevator (the stairs were extremely dark though- no motion sensor to activate lights) so it was a bit dangerous taking the steps.
The location is within a stone's throw of the Acropolis (we liked Syntagma Square area). Book it - you will love the place.
