The flat is in a very central location, and the charm of the area cannot be denied (trolleys going by downstairs, in between the water and Placa Rossio) The large windows in the living room and 1 bedroom give excellent light to the place and the high ceilings make it feel roomy, especially in the living room.
Pedro's dad was helpful to us during check in and then delivering some supplies in the middle of our stay.
The only downside was that as it was hot during our stay, the only thing that cooled the apartment were a couple of fans and then the nighttime air (read: no A/C). If you are ok with that, then no big deal.
The apartment had all the basics, was clean when we arrived and responses from the host were timely. Great spot!
