I stayed at Luis and Paola's place with 2 friends. The location was great for us. We really enjoyed listening to live music at nearby places and eating at the local restaurants. The apartment was very close to public transit for an easy ride back and forth to the airport (it is just as long to take a taxi and much more expensive). Then we were able to walk all over Lisbon from the apartment and take a train to Caiscais for a great beach day and another train to Sintra. You will not be able to stay at this apartment if you have a problem with stairs as there are many and they are steep. I just figured it was a little extra exorcise to make up for not going to the gym. We arrived in Lisbon really early and our host kindly allowed us to drop off our luggage so we could explore the city unhindered by suitcases. I would stay there again!
