Apartment was quite nice. Clean and tidy.
Keep in mind that Lluis actually lives in the apartment when guests aren't there, so you kind of feel like you're intruding in someone's house (the cupboards are full of clothes and the fridge has food in it).

Also, the shower is a bit complicated to use. Be sure to ask him to give you a full explanation on how to use it. My wife almost burnt herself during the shower at first because we didn't fully understand how to operate it.

We also asked for a late checkout (20:00), and Lluis demanded 60 euros for it... which I didn't fully appreciate, but we paid since we had no choice.

Other than that, the location is really nice, right next to the Montjuic (you can see it from the balcony). All the appliances are pretty new and operational, and he even had an ironing board which was good for me.

All in all, not bad.
