João was an excellent host, both very responsive and informative. We arrived slightly late to the apartment, but we received a warm welcome nonetheless from João's colleague Filomena. The apartment is very well situated — a short walk from Martim Moniz and Rossio train station, making it easy to explore the centre of Lisbon, and to visit places outside the city like Cascais and Sintra. We all loved Lisbon and I would thoroughly recommend staying with João!
