Starting without mentioning the staff, the hotel is in a convenient location for night life. Just two blocks from the theatres and six blocks from the obelisco, it could be a good option for a low budget stay. Breakfast is really good and has some good options for a healthy diet. The rooms are clean and spacious.
Now, mentioning the staff, it is impossible to give a higher rate to this hotel. To bad there isn't a 0 on the staff rating. We got there late night, and the guy at the reception was so rude; I wish I could tell the "right" words on this rating. It took us around 10 mins trying to find our room. If only this person was able to explain us where it was, we wouldn't be walking around with our heavy luggage! He didn't provide the A/C controls and wasn't that friendly when we asked for it, as well as for the WiFi access. The next morning, we waited around 15 mins for the waiter to clean our table to serve breakfast, she used one of the table knives to clean the mess (it was really disgusting). The only friendly staff were the cleaning ladies. They were more helpful than this "gentleman" at the reception.
If you are on a low budget, or for a short stay, is not a bad option, but please try avoiding the night shift, it could be really disappointing.
