Andre's flat was very very pleasant with attractive windows and a charming Juliet style balcony. A perfect place for us as a couple. We enjoyed peering out at the curious roof top cats and listening to the chatter of residents walking their dogs on this historic street.. Graca is a pretty area not yet ruined by mega-tourism, though it is certainly on the tourist radar..the tram 28 was always packed during the daylight hours. I would say relax in Lisbon - it can be very tiring negotiating the parks, museums ,steep hills and trams. Plan on doing half of what you researched, take a taxi when lagging and spend enough chilled out hours in Graca and the Villa Berta. As a host Andre was always available by phone and text.. And I would like to mention the restaurant Ti' Ascenciao on Rua de Sol a Graca. It is right next to the flat and is a small place, both simple and modern where the chef Joao makes very pretty and tasty food. Book a table, and eat the octupus.
