Everything was great, from the delicious breakfast (hot milk, pastries, salami, cheese, bread, tea, coffee, jam, cocoa, yogurt, cereals) to the room facilities. We had a suite, with two spacious room, fridge, safe, and microwave. Staff was extremely kind and helpful (well, with the exception of one member, otherwise professional, but not extremely pleasant nor flexible: he did not allow us to make an urgent local phone call from the reception but sent us to our room to make the call; also, he did not allow us to stay in our room longer than the check-out time (our plane was at 9 pm). All our friends who talked to other staff members were allowed to stay longer, without any additional charge. We were asked to pay $ 50 USD for a couple of hours, which we did not agree, so here we were, wondering through the city for a few more hours.
Other than this, the staff was very kind, humorous and always helpful.
I recommend this hotel. It is close to Avenida Corrientes. Also, to the Faculty of Sciences, University of Buenos Aires. It is clean and quiet. Worth the price.
