This flat is simply gorgeous! Even if it is not very spacious, I have to say that it is very well designed. We also LOVED the decoration (with all IKEA furnishings)!! The view is also amazing, especially with all the sunshine during this summer in Lisbon. The host is also very nice, when we arrived, he was waiting for us to at the front door and helped us moving up the luggage as there is no escalator.
Only one complain about the noisy neighborhood, as the room gets stuffy at night, it's sure that you will wake up several times if you leave the window open. This can be fixed if you bring some ear plugs.
