At this price, it's a bit absurd to charge 2.48€ per day extra per guest for tourist tax. This should be included. Yes it's in the house norms, but not everyone reads those necessarily before booking.
Also they charge 30€ extra if you arrive after 9pm, we were lucky to be there at 8:45. Further, they wanted to make us sign a paper that said 2 sets of keys received when they gave us only one. Fee for losing a set of keys is, again, 30€. It just feels like they'll take any opportunity to charge you extra.
That being said, the place was clean and quiet, and the location is great. Everything went smoothly but be aware they'll charge you extra when you arrive. In my experience most other places in Barcelona don't charge the tourist tax extra.
