Ana is an extremely sweet and kind host. Her place is clean and comfortable. I stayed for 1 1/2 weeks and it was great. It is about 20 min to the center of Porto by either train (10 min walk and 10 min train ride) or via bus which stops about 1/2 a block away from the apartment. There also are a couple grocery stores and a number of restaurants within a few blocks. The area is very safe. I was a solo traveler and felt comfortable walking home from the train at night. I highly recommend staying at Ana’s place
