Great unit for 2 couples. A bedroom and bathroom on each of 2 floors. Has an elevator too. Very clean and importantly has a great A/C as Lisbon can get hot. A bit noisy if you open windows as there is a club nearby and they seem to party until the wee hours of the morning, but the noise is contained if the windows are closed and they thoughtfully have ear plugs provided. Great location for walking to the main sights and restaurants.
