Cristina's qualities as a host are extraordinary. When we arrived she gave us a very warm and personal welcome. Taking a lot of time for giving us recommendations concerning Lisbon, restaurants, sightseeing (Alfama, Bica) and Bars/clubs (pink street!! Largo Intendante!). All her tips were amazing and led us to some places we probably never would have found on our own (mouraria, amazing shops around Pça. Principe Real).
The apartment is located in a very nice area. You can reach pretty much every place of interest by foot. And there is public transportation nearby. 10min to metro, 3min to busses. There are nice restaurants (you should try canela grill) and bars as well as a grocery store just around the corner.
The most remarkable aspect of the apartment for us was the tasteful furniture and lovely decoration. You can see that Cristina has made a large effort with choosing everything. The very well equipped kitchen and these little details made us feel comfy and at home there immediately.
We'd highly recommend a stay at casa do azulejo.
