We had a very pleasant stay at The Garden House! The nice thing was that we had our own space and own key so we could come and go as we pleased. The apartment is very easy to be reached and is surrounded by shops and little cafes to have breakfast. Also good parking possibilities. The public transport is very nearby and you can reach the centre of Porto within 15 minutes. We experienced quite soft weather so no cold for us (love portugal). The beds are very comfortable if you're not taller than 1.80 meters.
And on top of that Bernardo is a very nice guy!
