A very comfortable house within a quick walk to the centre of Porto. Our group was happy to have such spacious accommodations and 2.5 bathrooms! The restaurant just around the corner is also highly recommended.
The house manager who met us had informed us that we could call her anytime - however, we experienced a few minor inconveniences on our last day (tv didn't work, nor the outlets in the kitchen), but since we would not be staying longer we didn't request to have them fixed. We would still highly recommend staying here.
A general comment - if you arrive by taxi, make sure your taxi driver from the train station knows where they are going!
