I've been in this Hotel once. I had traveled to Barcelona for business and 3 persons were with me. so we took 4 rooms. it was amazing. every thing was clean and the rooms were cozy and quiet. when we arrived at hotel and fil out the forms, they asked us to deposit 60 Euro for each room for minibar and I payed them. I asked them to gave me a receipt ,but the man who was responsible in reception said: you don't need receipt and when you'll come for checking out, we will pay it back to you.
after 4 days, in early morning a van come to takes my friends and I to the airport. all of us came to lobby. one of us took the key cards and went to reception for checking out. I was busy with my phone and we got in to the van.
when i asked about deposit, he said: I didn't know about deposit and also Hotel's staff didn't tell me anything about that. we were far from the hotel and we hadn't enough time to return. I called them many Times and sent them some emails, but they never gave me the answer.
and unfortunately, because of the man, I haven't any evidence (receipt) to show.
