The check in was a bit frustrating. We were told at first we could drop our luggage at another location, but when confirming prior to our arrival was told it wasn’t an option and had to rent a locker at the metro station. The apartment itself was nice aside from the fact that the power went out when trying to use the stove and toaster. I would also suggest providing two keys because when one person leaves and locks the door, anybody on the inside is not able to leave... a bit of a fire hazard I would say. All in all, we enjoyed our time in Porto.
