We stayed at the Ibis for 5 nights. The location is really central and you can walk almost everywhere. The metro station is almost on the doorstep.
Apart from that we were a little dissapointed...the staff weren't particularly helpful, the breakfast was very average (pastries, juice, coffee on plastic plates and not much else). Safety deposit boxes are at reception and when we arrived we had to wait for one to become available (this was in the off season). It was freezing while we stayed there and the room had no heating. Our bed was rock hard and uncomfortable.
One isolated incident we experienced...during our stay there was some routine maintenance work on the water system overnight. A notice regarding this was pushed under the door, in Spanish which we managed to roughly translate. The work was due to finish at 5am. We got up to shower at 6am (early start for a day to Uraguay). While I was in the shower the water started running cold, then brown..it was truly digusting. I am sure this was an isolated incident and we were the first people to use the water after the work had finished but it was a terrible start to the day!
Buenos Aires is a fabulous city, loads to see and do and the hotel provides a convenient base to explore. If this is what you are after, then it may suit you. If you want comfort, friendliness and service then I suggest looking elsewhere.
