Nice, convenient location and very comfortable. 5 minutes walk from the metro station and 5 minutes from the river. Surrounded by shops and restaurants and very friendly people. There is a little market across the street where the owner is super cheerful and helpful. The kitchen was small but fully equipped with pots and pans, a coffee maker, toaster, microwave, and stove, plates, glasses, and utensils. The bathroom is modern and clean and stocked with shampoo, conditioner and body soap. The bed is super comfy and there are 2 nice chairs in a sitting area. There is construction happening all over Porto so there were a few minutes here and there when it got a little noisier than usual, mostly trucks coming by, but mostly not more than you would expect ordinarily for the location.
Overall a very nice place.
