We had a wonderful time staying at Anna and Klaus's apartment. The place is very clean and convenient. It is located in the pedestrian street in the heart of Porto, lots of cafes and restaurants around, so if you want to relax then you can just sit yourself with a nice cappuccino. The house is very stylish, the design is contemporary, you have all the materials you need for your stay. Even the space isn't very large, it is still suitable for our family. My daughter loved her spare bedroom, she would never want to get out of it :). Thank you Lucinda, for hosting us around and showing us the ropes. Thank you Klaus and Anna for the recommendations, we appreciated it. We had a lovely stay.
