Decent stay here if you're looking for something economical and in proximity to the center. The responsiveness and customer service is great, as this runs like a small business operation, not a private property owner--common in Porto (and often comes with a lot of communication but little flexibility). The team really takes care of the property and checks in on their guests. The apartment is much bigger than it looks in the photos, albeit with bare minimal economical furniture, which makes it feel a bit hostel-ish for my taste, as well as cavernous, like every sound has an echo... and it does, as you can hear everything in surrounding apartments (I could even hear the phone vibrations and notifications of the person upstairs). There's a very small bathroom, but the kitchen is spacious and has everything to cook--all good appliances--and a nice washing machine, super convenient. Wifi was fast and problem-free. Cleanliness was decent but not sparkling clean when I arrived (e.g. hairs on the bathroom floor and in the shower that weren't mine, but Ana who checked me in was so nice that I didn't want to complain). Overall, this place seems like a good choice for young 20-something travelers, but I personally felt a bit out of place here :)
