Nuno is an amazing host. He will show you around as soon as you arrive, will take the time to lead you trough the best part of lisbon on a map and will make sure that you see the essentials. You will feel at home at his place. The appartement is perfect, really well located, about a 15 min walk from downtown, the old unesco area, 5 min from the bar, right by a beautiful park. I would for sure go back there next time I go in lisbon.
