Jorge's place was absolutely OK. The apartment was tidy and clean, and his father Alberto welcomed us warmly upon arrival, giving us tips and practical information about Porto.
The price/quality ratio is OK but some improvements could be made such as providing a coffee machine (Nespresso or filter) so that one can just make a cup of coffee in the morning, and providing a bin in the bathroom.
It would also be better probably to put a screen in front of the glass windows between the room and the bathroom so that you don't wake everyone when you use the bathroom late at night or in the early morning.
The odour of mold in the apartment was not really enjoyable but it was mainly in the living room and kitchen. The rooms did not have that problem.
All in all, we thought the apartement was certainly OK for the price, though it was much more faded than we expected it to be.
The location is good, it is not too far from the main visiting areas of Porto and the square with the park make it a nice area to stay.
Thank you Jorge and Alberto for your hospitality!
