Cesar was very very very accommodating during our stay! We arrived several hours later than we were supposed to and we had to leave the apartment very early in the morning. He was extremely helpful on both issues. The apartment is lovely and located relatively close to the lively parts of Buenos Aires. The air conditioning was a life-saver. The only downside to the apartment is that you cannot flush toilet paper down the toilet at all which might be an issue for some people. On the whole, great stay, loved the apartment!
