We recently stayed at Salitre 100 and loved it! It is a beautiful, calm apartment with immaculate new finishings. Everything worked perfectly. The owner was very helpful, meeting us as planned, offering us suggestions for local restaurants and grocery stores and answering all of our questions promptly. The apartment is located on a quiet street and all the bedrooms are located on the back of the building, so there was absolutely no noise at all at night. That, combined with the very comfortable mattresses, made for excellent sleep. The location is located adjacent to great areas for exploration within walking distance, both in the Principe Real neighborhood and Avenida Liberdade. Many other great areas are within longer walking distance or just a quick cab ride away. A taxi stand is right on the corner. The added feature of a parking spot was great as we rented a car one day at the nearby Hertz to drive up to Cascais, and it was nice to be able to park overnight in the building as the Hertz had already closed when we returned. We absolutely loved our stay in Lisbon and would highly recommend this apartment to anyone.
