Abasto Hotel is a bit tired, the maintenance is not great and charging for internet access is a let down. But the bad side fits in this single sentence.
On the other side, the rates were fair, the room was huge, the staff is nice, the breakfast is great, and the location, even not being very central is still very handy, with a metro station just one block away and the taxis are very cheap in Buenos Aires. Abasto Mall just opposite from the hotel is also very handy for snacks and shopping.
Overall, I would stay there again despite it's bearable flaws.

Not only is the only Tango theme five star hotel in Buenos Aires but it gives free tango lessons every day at 7 pm for guests and paying a small fee for people not at the hotel ! you can also find the brand of tango shoes Madreselva at the tango boutique on the 1st floor!! more information at www.abastoplazahotel.com.ar and www.madreselvazapatos.com.ar

Although the hotel is modern, I loved it. I had a huge bedroom on the 18th floor (for smokers) including terrace and a small space with two chairs, a table and lamps. For those who love whirpool, it has that also. I do not understand those things so I did not use it. The room was neat and so was the bathroom.

The location is great if you like to walk in old places like Abasto. You can also walk from the hotel to the Carlos Gardel Museum located at 735 Jean Jaures.

The subte (subway) is two blocks away (to your left).

You can walk to get cheese and onions empanadas four blocks to the left from the hotel. They are great and very cheap.

Internet service is NOT free but you may choose 6, 12 or 24 hours of service. Do not forget to ask for the internet cable!!! Wireless did not work. The internet cable is free!

As with everything, some of the staff were nice and others were not too nice.

We booked this hotel at clickhoteles.com.ar. It was offered as a 5 star hotel & spa with swimming pool. The offer was a Deluxe Suite for U$82 tax included and buffet breakfast.
First: Spa? No jacuzzi, no dry/wet sauna. Swimming pool: yes, only open to 1PM to 7PM. The gym was clean and in very good condition. We had to go to the reception to get a key to open it (?).
Five star rating: Not really. The room was big enough and pretty clean, basic amenities, the smell of cigarettes was awful, the color TV set was old, and the furniture had seen better days. The internet was charged a $15 pesos for 6 hours. Not a smile from the staff. The buffet offered for breakfast was good.It was really very good the table of cheese and cold cuts plus a great red wine we had at the hotel restaurant for $70 pesos for both of us. It is a 3 star plus hotel. Comfortable and good located.
