Pedro's place is just perfect for a long stay in Lisbon. You are just next to the center, so you avoid the bustle of the very touristic places of Lisbon, and you enjoy a nice and quiet neighborhood.
The apartment is very pleasant, notably the small "closed balcony", very lighty and with a great view as we are at the 5th floor : just perfect.
Last but not least, Pedro is very reactive and helpful.
