Pedro was so nice - he drove us from the airport and we had a lovely chat. The apartment is small but all you need for your stay - the location is perfect and in the heart of Lisbon. I loved that the apartment had its own character and atmosphere and definitely is not an "IKEA place". One thing you should be aware, though - bring your own coffee and sugar :). And probably it would be kind of noisy (the emblematic tram passes right under the window :)) during the summer when windows are open all the time.
I definitely reccomend the location, the hosts, and the uniqueness of this place.
