Juan's place is great, located in a central area near a lot of things. You have a great view on the park and castle.
The metro is just 200m from the apartment and you can go take the tram within a few minutes. There is place to buy food just under the apartment. It is not the biggest market, but you can buy plenty of food for a short term stay.
It's Joana that did the check-in and she took the time to show a few places to visit on the map... it was really appreciated and added a human touch to the Airbnb experience.
Highly recommended. A+
