I just want to say that the apartment was everything it was portrayed to be and much more. Ralf was there awaiting my girlfriend and I even after we were stuck in traffic and delaying us nearly an hr. Furthermore we were checking in extremely early. Ralf took his time showing us the apt and explaining certain dos and donts in the neighborhood. I would stay there again in a heartbeat.
The apartment is in a perfect location. You are walking distance from many cafes and restaurants. If you want to travel to another part of town which I highly recommend, cabs are easy to wave down. Or you can be like us and walk nearly 10 miles a day. Haha.
There's a fairly new restaurant called la carneciera on Thames and charcas. We ate there our last night there. It was absolutely delicious! You should definitely call and reserve. I miss BA already. Can't wait to go back and trust me, I will definitely be trying to stay at Ralf's place again. Ciao.
