We really enjoyed our stay here! We were located very centrally in Porto, right next to Sao Bento station, which was very convenient. However it was not loud at all. The place was clean and had everything we needed. Finally, they were very accommodating and helpful - they gave us suggestions for places to see and restaurants, let us check in early, and let us leave our luggage during the day after our check out time. We would definitely stay here again!
