Carla's apartment was perfect for our first and definitely not last stay in porto! It is beautifully renovated (everything is literally brand new and tastefully designed!). From a proximity perspective great restaurants and shops are within a couple of blocks and all the main spots are within 500-800m or so. The exception would be the caves but we even took the time to walk there and back from Praca Ribeira. Communication was excellent from booking to checkout. Sonia personally greeted us upon checkin and the wonderful building attendant provided us many awesome tips and recommendations. Most especially, to take the bus out to the foz and matosinhos for a break from the busy city and experience the excellent grilled fish! The only small thing to note for travelers with little ones is a bit of noise in the late hours of the night from people coming back from a 'festive' night out. By no means a deterrent but rather gentle reminder its the heart of a very active city, so if you have young ones or are a very light sleeper be patient with the noise. Will absolutely recommend and stay again!
