We stayed at his place for 2 days - group of 10 ppl. Overall a good experience.
PROS for this place is its location - 1 minutes walk to Rua Augsta, 5 minutes to the main square Parc do Comercio.
Apt is in an old building but charming and nicely renovated - no A/C in the apt, well most of Europe don't have A/C. It was unusually hot in early August (110 F) and we have to sleep with windows open - hence a lot of noise at night and only two table fans provided. Lots of restaurants and food choices, souvenir shops and shopping etc.
The apt was well furnished and clean but lacked some basic amenities - no extra TP/no paper towels/trash bags etc. had to buy our own.
Overall, a great place. We didn’t had an excellent experience due to the unusually hot weather – not apts fault.
