Jose was very friendly and helpful in sharing a vast number of places to visit with the time I had as well as making recommendations for transportation. I found that almost everything I was interested in seeing was west of the apartment, which made navigating relatively easy (particularly because the river is a great point of reference).
I experienced a bit of a delay with the scheduled check-in process, but I felt fortunate to be able to let myself in and wait inside because they'd provided all the relevant information ahead of time.
This apartment was spacious, quiet, and decorated nicely. I didn't have any trouble sleeping, but I could feel the springs in the bed (for you sensitive sleepers out there). The bathroom had a bit of an odd smell (I think due to its proximity to the cafe), but I grew accustomed to it after a while. I also noticed some dark spots in the shower and on the wall near the laundry area, which could be nothing but might pose some issues for people who have respiratory sensitivities in the event the spots are mold/mildew.
Overall, I was very grateful to have an affordable, safe, and quiet place to rest at the end of a day of walking around Porto.
