I will set this straight.
This was the best airbnb renting experience of all I had. And I stayed at ~20 different Airbnb places both luxury and low-budget.
The place itself is great and has a nice view on the river. The location is amazing, it is close to a some of the best restaurants in Porto and there is a bus stop to the other cities right in front of it.
Every day Miguel sends you notifications about what's going on in Porto and what opportunities do you have today. That's amazing!
On the day of your arrival, you will receive a 10-minute lecture about all the best places and caveats of Porto. I think we have saved a few hundreds of euro just because of that.
So, don't hesitate. If this place is available, take it!
