We stayed 1week at pedro's appartment and we had a great stay. The view from the 3 balcons is simply amazing! Though, the view is so amazing, because Graça is a little bit higher topographically speaking, so the way from the meteo station to the appartment is hard (especially when you have to do it 3-4times a day). The appartment is clean and beautiful and the neighbours are like invisible, so no loud noises. The kitchen is a bit basic, but it definitely is good enough for a short stay. The check in and check out is very flexible, and pedro is very helpful: you can ask him everything at any time and he answers quick. What you need to be aware is that Graca is far away from sandbeaches: the nearest is Alges and even this small little beach is 40min away. Beside this, you can reach every place fast with the metro.
All in all we definitely had a great week in lisbon, and we are grateful that we could spent it here👍🏼
