Staff were attentive and friendly, and the hotel had good facilities, and was very clean. I would have appreciated a fridge in the room, as I travel on a budget, and often buy food for late night snacks or a quick breakfast, and the carpet was clean, but due to be replaced. Clearer information about the amenities on the website or in the room or elevators (great that there is a pool -- but where? Hours?) would have been useful.
The area around the hotel is clean and safe, but a bit bland; apart from a few buildings I could have been in any country in Europe.
Transit options for getting into the centre of Porto or out to the beach and aquarium were close to the hotel, but unreliable as far as the bus schedule was concerned.
Given the excellent service, comfortable room, and reasonable price, I would very happily recommend this hotel to family and friends or stay there again myself -- but I would allow a little more time to get to the old city (or take a taxi -- very inexpensive). Also, don't miss the roof bar! I only went on my last night, and really regretted not having gone sooner.
