We had an amazing time at Clara's place. It had all the amenities you could wish for: AC, fully stocked kitchen, two bathrooms, three bedrooms, and a small outside space to hang out. Also, ample free parking outside the door if you are driving. 20 minute bus ride into downtown Porto. It was very pleasant and cozy. Also, it is located in a non-touristy area but it's only a 10 minute walk to the river and very close to all the port houses. Very highly recommended.
