I stayed in Filipa's Airbnb for 2 weeks working remotely.
The room is perfect to work from, the space is well organized, with a nice desk and lot of power plugs. The internet connection quality was extremely good, I never had any problem if I used it extensively.
The neighborhood is full of nice cafes from where many digital nomads work, so it's easy to meet other people. It's close to the metro and to several different supermarkets.
The only negative point are shared spaces, both the bathroom and the kitchen are very old.
Dishes, pots and pans were quite old and dirty as well.
Since those spaces are shared by at least 3 people everyday they tend to get dirty quite fast and I think cleaning them once a week is not enough.
However I talked to Filipa about this problem and she responded quickly and solved the issue. Overall the price-quality ratio is good.
