We had a perfect communication with our hosts and a very warm welcome by Joana.
Despite the fact that we arrived late due to our delayed flight she took her time to explain everything en detail, asked if we want/need suggestions and insisted to not hesitate to contact her if we have any questions during our stay. Perfect!
We already knew Porto but she gave us some additional suggestions and managed a reservation in a restaurant where you normally have big difficulties to get a table within the next 2 days.
The appartement is located in a main street so you have to expect noise from the traffic of course, but we slept very well and when the roadworks are done the normal traffic should not disturb any more.
You can reach most of the interesting places within a maximum of 15min walk - perfect.
Short summary: For our next visit to Porto I will try to book again this location.
