This was such a great place to stay for our time in Lisbon! The location is central to everything, and even though it's in a busy square the windows are very sound proof and it's not loud when trying to sleep. It was very clean and spacious, and checking in was very easy. My only complaint would be the internet speed was quite slow, so working from there would be difficult. But if you're out exploring all day then it's no issue. Would highly recommend!
