Great 2-bedroom apartment on the edge of Arroios and Graça! We made this place our home for a month when we first arrived in Lisbon (ahead of moving into our own apartment). It was a great landing spot with fantastic views over the city. For grocery stores, you have Lidl and Auchan nearby. The coffee shop (Savas) at the top of the alley is amazing and friendly, and you're just a short walk from the Largo da Graça at the top of the hill.
Nuno gave us space and peace but was available when needed. He also came through to clean and change the linens/towels once a week which was wonderful. The one thing that wasn't quite perfect was the internet connection which was quite spotty. If you rely on wifi, it would be wise to bring a hotspot.
I highly recommend this apartment to anyone visiting Lisbon who doesn't mind climbing some hills :)
