This apartment was perfect for my family of 6 (2 children) for 10 nights that we booked. the location could not be better, and is no longer than a 20-30 minute walk to many parts of Lisbon.
The apartment itself had air conditioning in all rooms (good for the recent heat across Europe), a first floor balcony with a table for enjoying the views, and a top floor balcony to do the same. We enjoyed each evening with some wine and tapas before dinner, while our kids relaxed with Netflix on the television (a much appreciated "amenity" for parents with kids!).
Uber rides to almost anywhere were about $5-$7, even for the 6 of us, for when you are too tired to walk the hills of Lisbon. Since it is a hard street for some drivers to locate, use Rua Chagas for pick ups and drop offs, which is up the stairs outside the apartment.
Lisbon is one of our favorite cities in the world, and this is a great location to enjoy it from, we highly recommend!
