We have met Micaela's husband while arriving and had a really good welcoming! The place is walking distance from the metro station if arriving by bus or the airport.
Good wifi, kitchen well furnished, plenty of space for 3-4 people!
Unfortunately, there is a really bad smell due to the water running in the toilets. It is also a bit far from the old part of Porto and everything. Like the other comments, same dog kept us awake some part of the nights.
The price is honest, Micaela and her husband are really nice, but you have to know you will have to take the metro or others to go to the main parts of Porto.
