I had a wonderful 3-night stay at Luis' apartment. First of all, the location is incredible: just a few steps from Igreja dos Clérigos, Livraria Lello, and many cafes, bars, bakeries and restaurants; and only a short walk to Praça da Liberdade, Sao Bento train station , buses and the Metro. Second, the apartment building is special; it's designed by the same architect as Sao Bento train station and many other notable buildings in Porto (the facade and the staircase are works of art). Third, the apartment itself is spacious and stylish (it looks like the pictures) and the bed is comfortable. The place has everything you need, including a dishwasher, good heating/AC, a full kitchen, hair dryer and even an elevator. Finally, Luis is a pleasure to deal with: great communication, fast response and a simple, quick check-in at the apartment. I highly recommend staying here!
