We stayed here in early December. It is in a quiet residential neighbourhood, and a nice equal distance from the nearby lake and the core of Tandil--about a 15 minute walk in both cases. The pool is a nice touch and the owners are very helpful and friendly. The separate kitchen and living room on the first level make it a good alternative to a hotel room. It is not super modern or anything as with some newer hotel in Buenos Aires, but nor is it 30 years out of date. It is very clean. I'd highly recommend it.
