We stayed for four nights (3 generations) during the week, so ist was not that loud as on the weekend. But still there is noise in the rooms. When we arrived we just noticed that there is a bank holiday during the week. On this night it was more loud in the two front rooms. Anyway you will find your sleep if you are tired ;) The location of the apartment is very good! Many restaurants and walking distance to most things. The famous Tram28 stops very close... We loved the view from the other side of the tejo (take the ferry and have a nice meal near the big elevator). Never met Zita&Paula in person but everything worked fine and we got many information. Sadly we could only use the sweet balcony for breakfast because in the evening the smell and sound from the ventilations of the next restaurants were very strong.
