Joel's place is really comfy. It has everything you might need and extra! It has an incredible amount of kitchen utilities, loads of towels, iron, hair-dryer, and more! Wifi is strong and stable, tv is connected to internet so you can enjoy watching videos on YouTube etc. The terrace is killing! Sunsets are breathtaking there. The bed is super-comfy, the only downside is it's the only place to sleep so we had to share the bed with my friend.
Nearest metro station is just 10 minutes walking, huge shopping mall GaiaShopping is a longer walk or 3€ uber drive. There are a few places to eat nearby; we usually cooked at home though. My only inconvenience was the lack of a grocery store nearby.
The communication with Joel was really good, he always replied to us on WhatsApp.
No need to say that Porto is amazing so all we could do is enjoy.
