Lovely apartment (renovated, nicely furnished, in an old building with a character), amazing location (not center-center, but walking distance to everything), but - there is a long term construction next door. It's quiet on the weekends, but on the weekdays the work starts at 8am sharp and it is loud. I'm surprised that are no recent reviews mentioning it, as it looks like it's been going on for a while. It's a plus if you need to make sure that you do not oversleep and have time to explore the wonderful Porto.
