Great location, close to old town and comfortable accommodations. Air-conditioning is very helpful! Everything we needed... we are a family of 5, and the 2.5 bathrooms was very useful. Alex was SUPER responsive, and easy to work with. Entry was straightforward as well, though we had a little trouble with the lock on arrival. Once we figured it out it was fine.
If you stay, Mantegaria Pasteis de Nata is about100m away - not to miss, and very convenient for egg custard tarts. the steep steps help you work them off!
a few things to note: the apartment is at the top of 4 flights of stairs, as the description notes.
