Perfect location for a week in Lisbon, if you are without a car and focussed on food and exploring the city. Transport links (e.g. tram 28) are very accessible and you are on the doorstep of Time Out market to start your food tour. Equally near to ferry and train terminal for further afield. 20-minute taxi from the airport is roughly 12-15 euros (but you may pay more). Balcony is a nice touch overlooking pink street - for you people watchers!
Some specific mentions. Sound proofing is excellent, so don't worry about the location and noise from Pink Street. Bathroom is great and water pressure is perfect. Otherwise this is a great city lock-up-and-leave that feels safe and secure - elevator access to flat.
