I enjoyed so much my stay at Pensão Rosinha! The room is very comfortable and cozy, you have a city view both from your room and from the kitchen (and it is gorgeous), the apartment is very clean and very well organized, the room has everything you need (a chest of drawers, a hanger, a comfortable bed, and a mirror), and there is a heater for if it's cold. The location is superb - the pension is situated on a really quiet street near to the center and you also have a tram and bus/train station not far from the pension. You also have a bunch of nice cafes for breakfast purposes nearby. Paulo was very welcoming and provided me with a city map, a list of main sightseeings and good restaurants, which made my stay at Lisboa much more comfortable as I didn't have enough time to prepare for the trip.
Highly recommend it to everybody who is visiting the capital of Portugal! Will definitely stay there again!
