Highly recommending Diego's apartment. Palermo Viejo is great for tourists, in neighborhood you have everything you need for every day life, and from there, you can reach any parth of the town by public transport, which is available during all day and night. Also, Diego is available for all your questions and help during the stay. In apartment, you also have everything you need and have in your own home. If you dance tango, is also great place to stay, because there are a lot of milongas around, which you can reach by foot. We have been there 4 weeks, without any trouble. I hope we will come again.
