Joana helped us to check in, and she spent the time to give us recommendations as to what we should do and eat in Porto. The location couldn't have been more perfect, you're right in the city centre. The area (and all of Porto) felt very safe. The apartment was decorated beautifully, and the bed was perhaps the most comfortable bed that I've ever slept in! The towels were plush & hotel quality. The apartment is up a few flights of stairs, and there is no elevator, so do keep that in mind if you have mobility issues.
Thanks for a great stay Joana!
