My mum and I stayed in Sao Joao Ribiera 2 apartment for three nights. It was small & clean with everything we needed for our brief stay in beautiful Porto! I must say the beds were very comfortable ;) Apartment is close to the river and restaurants.
There was little bit of noise from surrounding bars in the evening and fair bit of building work going on, during the day. This didn't really bother us as we were out and about a lot and it's nice to see buildings being restored. Joao the host has been very helpful.
Thank you
