The house of Ana Paula and Joao was very nice and cozy, we really liked stay there. The place is not so big but very cute and intimate, with all the comforts you're looking for in a short holiday in Lisbon. The best way to see Lisbon is by tram and the house is quite near to the stop of Electrico 28 but a little far from the subway stop Rato.
Even that, the neighbourhood is calm in a residential zone, and Ana Paula and Joao gave us the best welcome, we really appreciated. I highly reccomend it!
