The stay was very comfortable. The flat is very centrally located, walking distance to the city centre. Paulo is very flexible and friendly.
We've stayed for a week trying to combine working and travelling. The internet connection was bumpy even though the flat had a glass fibre cable.
Paulo organised some pots upon request which facilitated cooking.
The ventilation of the house is rather scarce.
Overall we would definitely recommend staying there for a few nights but working remotely is challenging.
