Quite small — the pictures don’t really do justice to how small it is. The whole building seems to entirely made up of tiny Airbnb units. There’s a standalone A/C unit, but it doesn’t cool the room effectively, so we just left the (single) window open with a fan in it. I wouldn’t want to be here in the middle of summer. The stairs are *super* steep so if you’re carrying big luggage and not surefooted it might be a bit much. I’m an avid hiker, so when I say steep I really mean it. Overall pretty disappointed: the bed was uncomfortable, the coffee maker in the photos was replaced with a couple of packets of instant coffee, the lighting was awful, and the clip for the shower head was broken so we had to hold it while we showered. The saving grace was the location, which is super convenient and walkable to pretty much all of central Lisbon.
