Our stay at the Pinnacle was delightful! We had a spacious suite with two bedrooms for our family of four and it was modern, clean, comfortable, with every amenity we might need.
And the service -- wow! The staff was incredible and responsive. We messaged them a number of times and they were able to arrange transportation, make dinner reservations, deliver water and sodas to the room, and print out travel documents. They did so quickly and with a pleasant attitude every time, and never steered us wrong with directions or ideas for where to go.
The location is fantastic. We walked everywhere (even though the metro is close by, we didn't need to use it to get to the popular sights) and were at the Acropolis in about 15 minutes. Check out the rooftop deck -- the views are spectacular.
