Jose Carlos was very friendly, he gave us a very warm welcome. His apartment is located in a really cool neighbourhood, its about 20 mins walk from the very centre of Lisbon, but tram 28, the main sightseeing tram has stops nearby. It is also worth exploring the surrounding streets, Jose recommended us some good restaurants, we really would have missed out if we haven't tried some of them. Everything went smoothly, I can only recommend this host.
