It’s a family home, with a bedroom available for guests.
Google Maps & AirBnB do not give an accurate idea of the location, the Apartment block is to the right of a Mercedes Showroom next door, which is on the corner of Av. dos Descobrimentos and a roundabout. For some reason Google places it on the opposite side of the road. Thankfully the hosts provided a photos of the block which helped to find it.
The place is in the south of Porto, there is a bus service outside, and Uber and taxis are quite cheap if needed. But it is a long and uphill walk for those who want to try getting there on foot.
It’s clean, in quiet neighbourhood. It had a small balcony to sit and have a coffee or a smoke! With a decent outlook as it’s on the top of a hill. There are lifts to the 4th floor if you have a large suitcase.
