I can truely recommend the flat in the Alfama. It is a cozy, clean and newly renovated flat with a very tasteful modern "portuguese" interior decoration. All facilities you need for a stay in Lisboa are nearby, such as restaurants, a metro station, the Santa Apolonia train station, the tram 28, small grocery stores, a really nice bakery and various spots with great views of the city and the Tejo. I will come back.
