We had a very nice stay at Sofias place.
She was a great host: When we arrived, she explained a lot about Porto and even gave us a map.
Sofias house is beautiful and very clean, also the kitchen was well equipped,
Unfortunately, it was December, so we could not sit in the nice garden. Sofia gave us a heater for our room, which worked very well, only the kitchen downstairs was a bit cold.
The house is in the center of Porto and we could easily walk to all places of interest. In the neighbourhood there are a lot of shops, restaurants and a big supermarket.
We would totally recommend to stay at Sofias place.
