Come here not only because the location is central and the place is perfect (and honestly more economical) for large groups, but you should stay here because it feels that you have a personal concierge with Pilar. All of our questions were addressed and Pilar even helped us navigate the issue of a lost luggage.
Realistically though, the place is tuck hidden within the main area so it allows you to get some peace and quiet. Expect to get lost though given how streets are designed in Spain but you will get the hang of it.
Get your group together and book this place :)
