It was an absolutely terrible experience!
1. We're charged an extra 50 EUR for a stay in Barcelona, some local laws (first time heard about it, since the last ~10 trips to Barcelona).
2. House was completely smoked by cigarettes and Marijuana, and all my classes went to laundry after the trip.
3. No hair dryer in the house, my GF was forced to slip with wet hair.
4. The house was super dirty and damaged in some places.
Avoid at any cost.
