Spacious room, lovely apartment, excellent amenities, unbeatable location, great price, plus a wonderful host! I will want to stay there whenever I'm back in Lisbon (LOVELY city).
My only word of warning would be that it's quite a noisy street by night as it's by a bar. Closed windows help but as it's very hot you might prefer them open. This was not a problem for me at all, but it's good to be aware of this.
