Fantastic location, minutes walk from São Bento station. Beautiful room, great view from the balcony. Communication was great, practically immediate replies to any of my questions/requests. There's an elevator in the building which is a blessing after all day out. There's also a kitchen on the top floor (if you need a corkscrew for your bottle of porto :) )
There's an option of leaving your luggage after check out, it is only a few metro stops away. Everything is very well organised. The only downside is a quite late check in time but I still recommend this stay.
