The flat was a good size and in a very good location (though beware Lisbon is quite hilly!). It was great to be near Rossio, the Convento do Carmo and also walking distance to most of the sights in Lisbon. The upstairs neighbours were quite noisy during our stay, however I think it is another rental flat, so whether it is noisy will probably depend on luck! There were several restaurants and cafes nearby which was helpful.
