We really enjoyed our stay right in the heart of Lisbon! I was met by Nelson's stepfather upon arrival who explained everything to me, he was super nice and helpful with providing tips about where to eat etc. The apartment really has everything you might need (incl. kettle & toaster) and is a great place to relax after a day of sightseeing and walking. The location is just perfect:right in the center, the most important sights are in walking distance and there are plenty of pastelerias to enjoy pastel de nata (which we found in the apartment as a welcome gift :)). All in all a VERY enjoyable experience, I'll definitely be back to explore the city some more (and stay in the cozy apartment)!
