The apartment was absolutely great. Clean, easily big enough for a couple and equipped with everything you need for a great Air'Bnb trip to Porto.
The bed was big and comfortable, the furniture bright and new or well maintained, lots of natural light through two big balcony doors out on the small but great balcony overlooking the small backalley. Fully equipped kitchen (except dish washer) for cooking nights.
The apartment is perfectly situated to explore the city by foot, bus or train, starting 'on top' and located in an area with amazing bars, restaurants and cafés (literally all around). The square just around the corner has three bars with outdoor seating and the atmosphere in the evening is amazing, however not too noisy at night-time. Also, there is a great Co-Working space (Selina) just two minutes by foot.
Check-in was easy and in person, with clear communication and loads of tips what to see in Porto and where to go.
All in all we had no complaints and would return anytime as well as recommend.
If we would have to (really have to), name a small downside, it would only be some missing hangers in the bathroom (easy for one person, for two space is limited) and the proportion of bar stool to table (a little difficult to fit your legs under the table). But that is it.
