We really enjoyed our stay in the apartment. It's located in the historical center and we were able to get everywhere without using any kind of public transportation.
Dulce is really nice, she gave us some tips to visit, cookies and port wine. Communication was really nice and she was ok with our late check-in caused by our plane schedule.
Just be prepared to buy a bottled water, because the tap water is overchlorinated and tastes like swimming pool.
