This is an adorable little studio apartment on a busy main square right in central Porto. You're 5 minutes from old town and all the big attractions, and 5 minutes' walk the other way to cool, residential Porto. The apartment was so clean I could almost believe we were the first people to stay there. Check-in was smooth and the Aposentus team sent very detailed, easy-to-follow instructions plenty of time in advance. The charming windows look out onto the square, and do an amazing job blocking out the noise of the nightlife outside. Highly recommended!
