This is a lovely apartment - even better than it looks in the pictures. Lots of room for two people, light, extremely clean, with a lovely bathroom and a kitchen with everything you need in it.
Luis was really helpful and friendly.
Wifi worked, there was some information about the area, and contact details in case of issues, provided by Luis.
The location was great and we really enjoyed staying here - total bargain as well. We'd both definitely recommend it to anyone.
Just a couple of points to bear in mind. The apartment is split by partitions rather than full walls, which makes it lovely and airy but could be a privacy issue if that's something you worry about.
Also - central Porto can get quite lively at night, so if noise bothers you I'd pack earplugs. But that's not a reflection directly on this apartment.

All in all, a great place to stay. Thanks so much, Luis!
