My wife and I have rented homes/apartments in many countries (pre-post AirBNB), and this was easily the best experience we’ve had.
First of all, the location is perfect; close enough to the sights but just enough off the beaten path that the area doesn’t feel at all touristy.
Secondly, the apartment has been furnished with high end appliances, electronics, etc that it feel more like a home than just a rental.
Finally, the host has already thought of all the little things that make it extra special and easy :
-	Welcome bottle of Cava
-	Easy to use Wi-FI
-	Well placed signs explaining how to use everything
-	Printer at the ready so you can print out tickets and check in docs
-	All the kitchen/bath stuff you would need
We highly recommend the Airbau apartment.
