We are from Canada and stayed here with our 3 year old. The host was extremely pleasant and helpful. The kitchen was well equipped with everything you would need for a few days stay. The apartment was clean.
It was very cold inside at night, there are radiant panel heaters but they don't work well in the space so we ended up sleeping in toques and socks. As a side note, there is also no AC, which is probably something to consider during the summer months. Each room seems to have a fan however.
There was alot of noise until 3 AM, coming through the neighbors walls and from the street. We could also smell the neighbors food cooking while we were in bed. It was a Friday night, so maybe this is unusual.
The neighborhood is the only place in Portugal we felt slightly unsafe walking at night, compared to the otherwise super safe feeling we had through out Portugal. This is the only place we witnessed a substantial police presence. Something worth considering if traveling with small kids.
