The studio is perfect for 2 people (couple or friends), very clean and recently refurbished, confortable (with a good shower), and very well located to visit all the historic center by foot (1 minute walk from the train station), in a small and calm little street.
Diogo was really welcoming and available for any questions, very easy to communicate with and accommodating about the hours.
In one word, I really recommend this apartment and its host : thanks agaiun for the bottle of Porto wine and for your kindness Diogo !
