We were a group of 7 girls spending the weekend in Porto and we stayed in 2 of Gedeone's apartments in this same building. Both apartments were beautifully decorated, very spacious and with a spectacular view of the river. All rooms were very clean and we could find everything we needed in the apartments.
Eduardo was our contact the entire time and he was very friendly and helpful. He gave us lots of tips to visit Porto and made both the check-in & check-out processes smooth and easy.
The only advice I have, for people who might plan to sleep in (after a night out) or take a nap during the day, is to wear earplugs. There's a helipad on the river nearby the apartment and it gets very noisy during the day with the helicopters taking off and landing. Plus the traffic and the tram, it makes it quite impossible to sleep. But if you're a deep-sleeper or early-riser, this shouldn't be a problem.
