The apartment was very spatious and clean. I was expecting much more noise given the location in Barrio Alto, but it was not as bad as I tought. The only problem I faced was the sink in the kitchen that couldn't be used because all the water was somehow leaking under the furniture, but I'm sure that this issue can easily be fixed. Also it would have been nice to have some salt and sugar in the house, for when you want to prepare a quick breakfast. Nevermind
I would personally come back to the location when visiting Lisbon.
