Our stay at Daniel's place was great and he was a perfect host.
Our flight was delayed and we arrived at the apartment much later than we had informed Daniel, but he was waiting outside the door when we finally arrived despite it being very late.
The place was beautiful, well-equipped and clean and the balcony was great (sun until 2 pm-ish).
Daniel also sent us some great Porto-tips on restaurants etc. (We especially recommend the restaurant Tabua Rasa and the bar Café Candelabro - which is 2 minutes walk from the apartment).
