Irina's and Ricardo's apartment was awesome and we really enjoyed our stay there. The view from both windows is stunning and the apartment itself has everything one needs (including towels and chess)). We easily met up with Ricardo near the apartment (not far is a subway and also train station), who answered all our questions about Lisboa and recommended us some trips. It can be quite challenge to find the way to the apartment by your own, as it is situated in the middle of Alfama neighborhood, full of narrow, crooked alleys, but this is what makes the whole place unique and picturesque. You also mustn't mind to bend your back when you go to the upper room as there are low ceilings, but this gives to the place a cozy atmosphere. We appreciated enough natural light in all rooms and fresh breeze that can be let in by opening both windows in the lower floor. Also the cleaness deserves the praise. Except plenty of nice small restaurants in vicinity of the apartment, there is also a bikes and scooters rental with english speaking staff. Definitely recommended!
