Modern Apartment in a central district of Porto. The Apartment was clean and had everything you need for a city stay in Porto (modern living room / kitchen / bathroom ..). As it is located in a very hipster like area of the city, of course there is a lot of nightlife going on in the streets nearby and therefore you might have to sleep with closed windows, especially in summer.
The only real little issue we hade was luggage storage at our arrival. If you arrive before checkin time (15:00 in our case), there is no possibility to leave your bags in or near the Apartment. There is an office in 2,5 km distance where you could leave them (~30 min walking time) and there are some paid options of public luggage storing in the area, but all in all you might have to time your arrival pretty much on point, to avoid further inconveniences.
