I try not to be too enthusiastic, but this little appartement was just perfect for my trip!!
located in the heart of the city, it is so easy to get there (the metro is 8 meters away from the flat), it is central but not noisy in the night, everything was super clean, sandra super nice and reliable; there was a welcome-snack and a folder with adresses and advices, the wifi worked briliantly ... well and then there is porto!! maybe one of the most beautiful and warm-hearted city I have ever been (and i have been to ALL european countries!)
