We enjoyed our week-long stay at Gabriela very much, the house is decorated with taste, fully renovated and in a quiet street very close to many buses, cafes and bakeries on Rua de J. Dinis. Easy location also if you intend to visit Serralves Foundation or the beaches (we had a lot of wind that day) / Matosinhos.
We were welcomed by Teresa with plenty of useful information.
From the bar/kitchen side, you can look down at the garden, reachable by outside stairs, but we were too busy with visits to Guimarraes and Douro Valley to take advantage of it. Next time maybe!
