We very much enjoyed our week in Buenos Aires at Laura's apartment. The space was great for a couple, in an excellent location close to transport (surface rail, metro, public bike scheme, and many buses), restaurants and shops. The area is great, we felt at ease returning late at night on foot.
The shower was hot and the mattress very, very comfortable. We slept so well that week. The kitchen was functional, though a little short in some departments (e.g., bowls, spoons).
Laura's guidance and availability (via messaging) the night we arrived was very friendly and reassuring.
The downside was that we felt we needed to sweep the apartment to make the place or own.
