Great stay, the studio apartment was perfect for two people for three days. The studio was as described and looked like the photos. It had all the essentials that were needed. The bed was very comfortable, there wasn't air con but the shutter for the windows helped keep the studio cool and we had no troubles sleeping, I think for hotter weather (25 plus) a fan may be needed. Although the studio is quite central you do have to walk up a sloap to get there from the centre and wasn't possible when carrying shopping, but noticed most of Porto seemed to be on a sloap! Nearest metro was Carolina Michaelis, it was approx 10 minute walk away and you're in the centre within 5 mins / few stops.
