Staying in this unit was exactly what I was looking for in Lisbon. Yes, it is small, but being a solo traveller, it was perfect for me. While there is no AC, the unit doesn't get much direct sunlight through the window being that there is another building very close to block the sun, so it was always nice and cool in the room. Plus, a fan was provided. It was not too far of a walk to the train either, and the nearby miradouros were stunning. My only problem with the unit was the device in the shower to catch sand particles, as it ended up slowing down my entire shower to the point that I would have to stop, wait a little bit for some water to drain, and continue. But it wasn't that bad, and I'd love to return!
