I've spent one night at Nuno'appartment, and I would recommend as a nice place to young people for a couple of days, since it is really well located, really close to Bairro Alto, and also affordable. It is actually an apartment whole rent for travelers, so you will have your freedom, but do not expect the kitchen and bathroom really organized and cleaned, side there is no local leaving there. However, it was indeed what I was looking for just one night, so I recommend.
