We spent 1.5 weeks on workation at Rui's apartment and were very happy with our choice. We needed stable internet and space to work and with that we had no problem. There are several good restaurants right below the apartment for a quick lunch, and for breakfast you can go for hot buns right next door.
The location itself is very good - you can easily get to any part of the city, the metro and bus stops are close to the apartment.
