I stayed in Simone's apartment for a month in September/October and found that it was in just the right location: far enough away from the tourist spots to be quiet but within walking distance of many of the sites I wanted to visit (and close to many bus/metro transportation options for those I couldn't walk to).
There were many restaurants and grocery stores within walking distance of the apartment as well. Simone met me at the apartment when I arrived; check-in was quick and easy, and Simone had lots of good suggestions for places to eat nearby.
The wifi was impeccable; I work while I travel, and was able to access all of the sites I need for work as well as conduct Zoom meetings during my stay without any issues. Of the three Airbnbs I stayed in during my visit to Portugal, Simone's apartment was the only one at which I never needed to use my mobile hotspot.
The apartment itself is charming - clearly a lot of thought went into making it homey and comfortable. It felt like a real family home, rather than an apartment furnished entirely by Ikea, as some Airbnbs are.
Everything I needed was there (extra towels, some spices, starter coffee pods, etc). It is fairly quiet as well - I was able to hear some of my neighbors from time to time, but this was minimal. The windows also blocked out a lot of traffic and other street noise at night.
Overall, I was really happy with my stay and would highly recommend this apartment to others!
