The apartment is stylish in a recently renovated building. The pool area was nice also.
The Graca is a neat neighborhood. It's close enough to the cathedral and St. Jorge's castle that you can easily walk there, but it's not completely packed with tourists. There are a bunch of nice cafes, especially for breakfast and coffee. The apartment is also a couple blocks away from a cluster of Indian and Middle Eastern restaurants.
Alex and his team were helpful. We communicated with WhatsApp which I always find helpful when traveling.
