Beautiful apartment with everything you need. Unlike other reviewers, we had plenty of hot water and the unit was fully stocked with dishware and other items. Tons of storage. The bedrooms were spacious and comfortable. The location was great: one block away from the Cais do Sodre station, linking you to Metro, buses, trolleys, trams, and CP regional train. The apartment is on the 1st floor (2nd floor for Americans), with a great wrap around balcony overlooking the Jardim Dom Luis.
Other reviewers noted the noise. Yes, it is noisy. You absolutely MUST wear ear plugs. There are numerous bars in the area (the Pink Street party zone is just two blocks away). Plus, there is a metal seam in the road directly below the apartment that makes noise every time a car drives over it. That being said, with ear plugs, the sleeping is wonderful and room darkening curtains make it even better.
Overall, you can't beat the value, location, and space.
