The staff is good and professional. The hotel it is sort of new buy apparently not well built. For instance, it has double glass windows, but they don't close properly, so cold air still gets inside. The sewer pipes do not properly stop the smell from coming out. I had to change the room once, and in the second even though it was better, every now and then I could smell the waves from the pipes coming back. More or less, it is comparable to an old 3 stars hotel in the US.
Finally, and this is really bad, because non-Argentinian residents do not need to pay VAT one has to present a proof foreign residence. They copied my credit card, including the security code!!!! I had to cancel it. They argued that it was the only way to prove that i don't live in Argentina, which is not true because I've been in like ten Argentinian hotels and that never happened.
