There are different types of air bnb experience.
This place gives you the more sense of privacy and hands off experience of air bnb. (As opposed to the host living nearby or meeting you)
For us this was great- we could check in early which was very helpful- and were able to come and go as we pleased with the full self contained apartment experience.
The location is great we explored Porto on foot and only got the metro to and from the airport (which was very convenient with no changes!)
The apartment had everything we needed and was nice and clean. We struggled with quite lukewarm ‘hot’ water- so our showers weren’t the nicest. The hosts tried to direct us as to how we could solve this problem but it wasn’t straightforward.
Other than that a fantastic place I would recommend to explore a beautiful city!
