The apartment is overall nice and matches the photos and Airbnb description. It's conveniently located in Alfama: the area is very quiet at night, which allowed us to sleep well. Both David and the concierge company made the check-in experience very smooth and pleasant.
Despite looking clean at a first glance, my wife and I noticed how several corners were dusty, and not cleaned property. Both the blankets and towels had stains.
However, the main obstacle we encountered was our WiFi connection. it stopped providing access from day 2 to day 5 (our last day). During this time, the host wasn't responsive, and the concierge company didn't know how to help.
To conclude, we enjoyed our stay, but would probably opt for a different accommodation the next time we visit Lisbon. Also, we don't recommend staying here to those working remotely, as WiFi connection wasn't reliable during our stay.
