The flat is really great value: location is absolutely superb, Paolo was easily reachable (we agreed to use Whatsapp) and the flat met our expectations overall.
The neighbourhood is at the edge for the touristy areas, so it is easy to walk through the city center and still benefit from authentic restaurants in the evening. The viewpoint Santa Catarina is a stone-throw away. The historical tram line 28 is very close. Hint: go down the hill to the stop just before all the tourists get on to increase your chances to sit down.
Paolo did not have a lot of time for us, but still pointed us in the right directions and provided a list of the key things to know about restaurants, viewpoints, visits and nearby amenities.
