Nuno us an excellent host. The place was exactly as described. Very central and a short walk to the main attractions in Lisbon. The place is very accessible by public transit - the famous Tram 28 is just a hop and a skip away and two major train stations (Martim Moniz and Rossio) are a short walk away.
We ran into one unexpected challenge and Nuno responded right away and in a very hospitable and kind manner, setting a high standard for AirBnB hosts :)
