Luís was very helpful, he interrupted his vacations to pick us up at the airport, which is hospitality beyond the call of duty. He also gave us a tour of the neighborhood and many great tips.
The place is small and cozy, located at the top of 2 sets of steep stairs, but that's how Lisbon's nicest areas are, so you end up walking up and down stairs all day long, so two sets more are really not a big deal, and the prize is a wonderful view of the Tejo.
The place is located in Alfama and you can go to Fado places, walk uphill to the São Jorge Castle and several very nice view points. It's a bit harder to get to Bairro Alto and other parts of the city, but the place is close to the Metro and tram lines, which are very good and making moving around very easy. Regardless, we often opted to walk through Alfama instead, passing by the Cathedral on the way to the city center.
