The hotel is an oasis in the heart of busy Athens. No noise, very nice patio with a large sitting area surrounded by vegetation, very comfortable bed and pillows, daily change of bedding and towels, very large bathroom with so many big mirrors, extremely friendly and helpful staff, good breakfast, and complimentary water. Front desk open 24 hours. Checkout at 12 pm. 
Cons: dirty/stained carpet, no shelves in bathroom, no storage in spacious bedroom (just a few hangers). 
All in all great place to stay in Athens at an affordable price.
