We had a lovely time staying at the apartment. It's bright, clean and very practical for 3 couples. During weekdays it can be a bit noisy in the morning since most bedrooms are directly or indirectly facing the street, but we got used to that after the first night. Closing the shutters and windows at night does help a lot.
The apartment is at walking distance to some great restaurants and has a few small grocery stores around the corner, as well as a pastellaria (for your pastel nata (custard tart) and bica (small coffee)). Upon arrival we also received some advice for a couple of places for drinks and good food. We got to sample a couple of them and there were all good or really great.
The apartment is located near the sights in the citycentre (walking distance) and has a metro-stop nearby (Avenida). This is all very practical.
It was very kind of Joao to allow us to leave our bags in the apartment on our departure-day so that we were able to enjoy our last day without having to carry all our bags.
If/when we come back, I would definitely stay in Joao's apartment again. Thank you for having us.
