My wife and I thought that Vera's place was absolutely great. You have a fifth floor (sixth floor in USA terms) penthouse with a relatively large south-facing terrace that gives a nice view over the roofs of the neighborhood buildings. Thus no noise from neighbors walking on the floor above. In fact, no noise problems at all. The neighborhood is probably the best in the city. One of advantages of this neighborhood is that it is not overrun by tourists. If you meet someone in a café or store, it is likely to be someone who has lived long term in Lisbon. Vera's apartment is very well located. Within a 3-minute walk we had a gym (2 week membership at very low cost), a dance studio (we took salsa lessons), a grassy park, many restaurants, bakeries, a supermarket, coffee shops, and a metro stop. Using the metro you get to the major tourist areas in 10 to 15 minutes. On a couple of days when we used the air conditioning it worked fine. In short, Vera's apartment is highly recommended.
