Staying at Juan's apartment in Bairro Alto was such a pleasure. He made us feel very welcome and went out of his way to make sure we were comfortable. He even was so kind as to wash and fold a load of laundry for us. Moreover, the location of the apartment is perfect -- close to the castle and to Rossio (the main square in Lisbon), yet down a very quiet street. I would highly recommend staying with Juan on your next visit to Lisbon.
