This is a fairly spacious apartment in the heart of the historic centre of Porto, after a short period of time we were able to get our bearings within the city and walked to different areas of the city for the majority of our stay.
Mathieu was very accommodating, after meeting at the apartment and answering any questions we had it felt as though we could have contacted with any problems (we didn't have any problems). We also took a dinner recommendation for one of the nights which we enjoyed!
For us there were no issues at all, but to note for others there can be a little bit of noise occasionally in the morning as traffic can build up moderately on the tight streets, there was also a little noise at around 11pm (possibly the nearby restaurant emptying bottles) on one of the nights, this was also of no problem for us as it was only brief (10/15mins) and we were not in the apartment at this time for the other nights. The street still seemed quieter than most, and a lot quieter than some of the more bustling streets where some hotels were located.
I would definitely like to stay here again if I am in Porto!
