We had a great time at Sara's place. She's managing a few more apartments in Porto but welcomed us personally at our arrival and took all the time needed to show us around. She's very communicative and always replied quickly. She even speaks almost perfect German besides alot of other languages. We had a minor technical issue with our appartment but it was solved very quickly. Sara arranged a day-trip through the Douro valley for us that was just perfect and we can highly recommend it. The appartment itself has everything you need, was absolutely clean and is located perfectly. Everything is in walking distance and there are really great places to eat less than a 3 miniute walk away.
