Basics. If you're gonna be in Barcelona a short time it's good. I would not recommend for more then a long weekend. beds are not comfortable.
I would not count the 3d room a useful, it's so far from the AC it gets really hot. we just used it to store our luggage.
The host are very responsive during the stay but before hand make sure you let them know how you want to be contacted since they don't always use this app.
