My girlfriend and I stayed in the apartment for 10 days because we had to defend our thesis at our University. We were therefore looking for a place near Bairro Alto, so we could celebrate our graduation, whilst not having the noise of the main party district. The apartment was honestly perfect! We weren't bothered by any noise at any time, while the bar street could be reached in literally a few minutes. The apartment itself is absolutely beautiful, clean and very typical Portuguese. Also, Catarina and her husband are very helpful and relaxed people. I would strongly recommend anyone staying here that's looking to stay in the centre of Lisbon, while having still having peace and quite. Thanks Catarina!
