This is great place for stay if you need train station at early or very late time. Also I really loved there's Lidl store around the corner.
Room itself is cozy and clean with very comfortable huge bed and nice bathroom.
House's host left us very detailed plan and a key since we arrived late so there was no problems with check-in.
We arrived when it was very cold in Porto so it was cold inside too - typical problem in many places in Portugal. Also walls are quite thin - you can hear neighbours when they talk loud.
On the map it's bit far from the centre but it's quick to walk and I enjoyed silence at night.
