Great apartment. Great communication by Joana - very professional, a quick and extensive tour of the apartment, codes, passwords, contact details, and even a small guidebook full of personal food spot recommendations. Also an introductory bottle of wine - nice touch;) The apartment itself is well-equipped. Interior is a bit dated, but well-maintained and we didn't have any issues comfort-wise.
The best feature is location - nice quiet neighborhood, but right next to the city center and we walked by foot for all of our engagements.
The one drawback is soundproofing. We could hear everything from the hall and apartment upstairs, but thankfully were so tired that it didn't affect our sleep. For lighter sleepers I would recommend a pair of ear plugs. Again, I would like to stress that there no noise or loud neighbors, just occasionally you would hear someone coming home at night or you would hear conversations during the day, but nothing really disturbing. And anyhow there was the same issue with all of the apartments we stayed in in Portugal.
