We stayed for two months. The location is really great. Close both down to Sao Bento and towards the city center, and the other direction towards lapa or campo de orique is also amazing surroundings as a tourist or long stay.
Internet was really good, works perfectly fine for “working from home”. One thing we missed as a long stay guest was a bigger fridge and an oven. But other than that it was OK equipped in the kitchen.
The tram is going just outside, so it might be good to know if you need it really quite when you sleep. It didn’t effect us, but I can see it could bother some. But overall we had a really good stay and the host was really good at communicating.
