Stayed at the hotel last month. Managed to book 3 nights for 200 euros - it was great value. Very clean and modern looking. Agree with other reviewers regarding the walk, but it's a walking city and was fun to get around on foot.
The only criticism I can offer is that the front desk, trying to help, directed us to a bus terminal on the map, instead of the main bus terminal, for a trip we planned out of the city. Turns out the map was wrong and no bus was ever going to arrive at the apparent terminal. Was a small twist in the day, but we still managed to have a great day in Porto. Would certainly stay at the hotel again.
