Hotel was nice, but I had a bad experience with hotel staff. Day staff were very friendly and very helpful. Night staff keep door locked and will not let you in until they check the hotel records. I had to stand outside for 30 minutes (at 1 A.M.) while the man tried to determine whether I had a room at the hotel or not, even after I showed him my i.d. and hotel card. He called several people and looked at papers at the front desk for 30 minutes. I don't think he got an answer. Finally, he gave up trying to figure out if I really stayed there and just let me in and gave me my key. Idiot. What kind of hotel doesn't keep records of who stays there? What kind of staff would make a person who stays there stay outside for 30 minutes? I'm a professional and don't look suspicious. And at the end of it all, he never determined who I was - he just gave me the key I asked for 30 minutes previously. Maybe this is just Argentinia, but I was not impressed.
