Stairs! As others have mentioned and host has- Be prepared to climb stairs! Luckily my wife and i are fit and had no problem with the stairs. We found it a great way to burn off the calories. :) Fantastic location close to a lot of monuments, cafes, and restaurants. The metro is easily walkable with luggage (fyi to tourist) and so is the city. The unit had everything we needed for a comfortable stay-AC, comfy bed & pillows. Nice view at night of the skyline. If you’re heading to dinner be sure to make reservations everywhere. We had no problem with getting one. The recommendations in the welcome book helped a lot, too! For great cappuccino be sure to check out BEN Cafe and Ditta Artigianale! The host was quick with responses and provided great service!
