Adriano and Daniel were great, super hosts in the making to be honest, they had maps and a handy manual neatly put together, that they sent us in digital format, were always prompt to reply to our messages and help us.
Flat is in a great location, close to subway stations, grocery stores, attractions, everything we needed. It's on top of a hill, but that's the whole city of Porto :D
For us, that heavily rely on the hosts' internet connection to study and work, this was an A+ stay, no issues there whatsoever, speeds were around 60 Mbps.
Kitchen was equipped with everything we needed too, dishes, glasses, cutlery, cooking pots, oven, microwave.
Shower was also great and deserves a mention here, just make sure you put the rug on the floor before using it to avoid a small bathroom flood.
If you're a couple, make sure you're ok with separate beds, and if light bothers you at night, perhaps you'll be better off covering the window that doesn't have blinders.
All that said, staying there for 13 nights was a very positive experience!
