We'd thoroughly recommend The Blue House. The apartment is in a fantastic central location, and we were able to walk to local bars and restaurants, as well as the waterfront . It's a stylish and peaceful place to relax in the evenings and we really appreciated little extras like the book of tips for guests and of course the Nespresso machine.
We had a small medical situation while we were in Lisbon, and Ines and Antonio were hugely kind and helpful.
