Our stay in Porto was delightful and being in such a well located place was definitely one of the biggest pros in our travel. Everywhere was reachable within 10 to 20 minutes walking from there - and that includes even the city of Gaia across the Douro River! There are plenty of coffee-shops, restaurants and supermarkets in the area as well.
The train and bus station are not further than 10 minutes walking, and the subway station that leads straight to the airport is also very close to the spot.
Despite being a shared apartment (in total I guess there are 4 rooms), the place is calm and we never had any issue finding a toilet free or space in the fridge. Since the location is very central, it is a bit noisy during the day, but the nights are mostly quiet.
The main con was a massive construction lot right next to our room, but João offered us earplugs - at first we declined but then bought our own the next day.
The accommodation itself was good, the bed-sheets and towels were smelling very good and it was noticeable that João would take care of the general cleaning of the house - the toilet paper rolls were always sufficient, the foot mats on the bathrooms were constantly exchanged, the ashtrays were emptied and the trash was taken out.
For those that are a bit claustrophobic, the small bathroom door lock can be tricky, since it requires some patience and skill to either lock and unlock it, meaning that more than once it was possible to hear someone having trouble to be able to leave it. The small toilet also doesn't have a main window, which makes it humid - and sometimes smelly - since the exhausting fan is not that efficient.
João was very nice to us since the beginning and showed a lot of attention asking us about our general experience during the week - our check in was quite late at night, since our flight who was originally supposed to land around midnight got delayed and the subway wasn't operating anymore. Our check-out was also very flexible. In general we had no issues regarding security or privacy in our room, and João guaranteed that our stay was comfortable and safe.
The terrace is a nice place to spend some time drinking wine, smoking a cigarette and or just be chilling. Despite not having a pretty sight, it was good to have some time there every now and then, hearing the seagulls and enjoying the nice weather of Porto.
In sum, we had a great time in the city and the place we stood played an important role in the overall experience, for which we are satisfied and thankful to João. We hope to be back soon!
