Carlos' flat in Lisbon was beautifully furnished and conveniently located. It wasn't exactly located in downtown Lisbon, but the transport links were fine (when there wasn't a strike) and my friend and I were actually able to walk most of where we wanted to go.
Rui showed us the apartment and made us all feel very welcome and gave us plenty of advice about what to see and do in Lisbon. As well as the flat being filled with many travel guides and local flyers of "what's on" in Lisbon, the kitchen was also generously stocked with plenty to get you started, which was a pleasant surprise to us!
I would recommend to anyone who is travelling on a budget and who doesn't mind taking public transport. Thanks!
