Pros: the space is lovely and the apartment looks beautiful, with the high ceiling and historic features of the building. It was also very clean. The location is very very central and convenient to walk about Porto - communication was very clear and easy and the check in process was simple. I was able to check in half an hour early which I appreciated!
Cons: the location of the apartment is above a bar - a couple of other reviews mentioned that with the windows/shutters shut the noise didn’t disturb them but I unfortunately found that this wasn’t the case for me. I’m not a particularly heavy sleeper but the noise kept me up until 3am most nights! Something to consider if you are looking for peace and quiet. I also thought that the beds were very uncomfortable and I wasn’t impressed with the bedding, which was very thin sheets and a duvet with no cover. The hot water in the shower only seemed to last 5 minutes at most - not long if you have hair to wash!
If the cons don’t bother you, and you’re expecting to enjoy Porto’s nightlife I would stay here, but it wasn’t the right place for me personally.
