Dulce's flat is spacious and well equipped: there's plenty of kitchenware, a huge wardrobe so you don't have to live out of a suitcase, enough duvets/blankets that you'll never risk being cold at night (we really appreciated this), a comfy sofa, clothes-horse, good wifi, etc. The living room leads to a small yard which is on the rear side of the building, meaning it is shielded from street noises; in fact, the entire flat is fairly quiet in general. It should be noted that the corridor, kitchen and bedroom are darker than photos might suggest - you need to turn the lights on in order to see properly. Then again, these are more "functional" spaces where one typically doesn't spend much time during waking hours, whereas the living room receives plenty of natural light during the day.
We found the location of the flat to be excellent: we didn't use public transport but we did see that the area is well connected, and half an hour's walk will easily get you to the Praça do Comercio, Parque Eduardo VII, Miradouros, etc. Just as importantly the street and surrounding area themselves are great, bustling with people and local shops. Special mention is due to the bar/restaurant that is literally next door, where you can savour Tia Celeste's tasty, cheap food and characteristic atmosphere. The pastelaria across the street is also excellent.
Finally, the logistics of our stay were very smooth: check-in and -out both went without a hitch, and communication with Dulce and/or her husband was easy and quick both before and during our stay.
