Staff were great and we're very accommodating. We arrived at 3pm and unfortunately, our unit wasn't ready yet and we couldn't get in till 3:40pm. It would have been great to have been notified if they needed more time. The staff did let us rest at another unit while they were preparing ours. In all fairness, I believe they were replacing mattresses in the whole building that day so I understand if they needed more time. Place was great for multiple people but the main shower was pretty small. There's also a tax to be paid in cash which were not aware of and they asked us to pay it when we arrived in person. Again - would've been great to get a heads up on that. 
Porto is very hilly and this location sits at the bottom of the hill and is basically near the entry into the main part of town. It's quieter for sure, has an amazing view of the iconic bridge and there's still plenty of activities close by. However, you should be aware that there is quite a steep trek to get into the upper portion of town from where this residence. There is a fee based elevator close by however.
