The little apartment has a very good location and it's good for a couple of nights in Porto. it is perfect for two people who don't spent a lot of time inside the apartment. the building is very noisy, you can hear people walk, talking, etc. when someone cooks in another apartment, it will smell in your apartment too.
besides these aspects, the communication with Marta was always perfect and she was helping any time. check in & out we're no problem at all.
