Carolina's place was a perfect base for me to get some work done and explore Porto. It's centrally located within blocks of metro (the station also has luggage lockers) and a short walk to many of Porto's main sights. The apartment has all the essentials and is cleverly laid out. The large balcony is a great feature. Some serious construction going on close to the building, but the sound is completely blocked by the double pane glass - not an issue. A glitch with internet connectivity and water, but absolutely out of Carolina's control. She is a wonderful host - welcoming, hospitable, and very responsive (had someone working on the internet issue immediately). Overall I had a great stay and it was a pleasure being hosted by Carolina.
