I highly recommend studio on the park. It’s an ideal base for touring the city. Public transport is easily available, which we didn’t need a lot of anyways as lots of tourist attractions in Ribeira (Porto historic district) are walking distance away. As is the Duoro river along which there’s lot to do and see. As are restaurants and bars which surround the location. It can be a bit loud at night. I was intrigued to discover that the locals seem to only start to go out on the town about 11pm and then seemingly at 1am the partying is in full swing. Especially Saturday night. The shutters in the apartment do a remarkably good job of keeping out not only noise but also light from the city. I appreciated the washing machine which is great for longer trips and avoiding seeking out public laundromats.
