This is a decent enough hotel but the staff are what really make the difference.
My wife developed laryngitis shortly after arriving in Buenos Aires. Diego and the rest of the staff were extremely helpful and attentive. They phoned taxis and doctors for us, helped us change check our changed flights and generally helped us sort ourselves out during the stay. It would have been a very different experience without their help.
The hotel was well located for getting around town and was good value for money.
It's easy to walk to town from there and it is handy for La Recoleta.
The only downside was that on our second stay there we got the very last room (which is obviously kept in reserve) but they did offer to change us the next day.
I'd just like to say another thank you to Diego. You really made our stay enjoyable!

The worst thing about this hotel is the horrible sound proofing. When you are in the room and someone does something in the room next to yours or in the corridor - you can hear everything. of course, after some time you get used to it and you feel like at home when your family members walk arond in the eveing, but in the beginning it was like a shck (although I read reviews at booking.com, but still it was a big surprise for me). The breakfast was also quite average, I do not remember any hot meal (except toasts). Of course, normally you do not need to eat too much but for some people it can be important. However, the location is very nice, you can go by feet to most of attractions, and if you can not or do not want to go by feet you can always choose a taxi as an option to travel everywehere for a bit of money. But I would not recommend this hotel, despite it good price.
