My girlfriend and I had a great 1 month stay at Carmen's. Communication was great even though we didn't meet the host, she made sure Aida who was on site was available to help us. Great location, on a quiet street but just a few blocks from the lively areas full of nightlife and great restaurants. Very fast internet and great cable TV selection. The rooftop was awesome for sunset views and enjoying a glass or two of wine, as was the apartment balcony. Friendly neighbors in the complex as well. The apartment felt very homey with a lot of personal touches, unlike a hotel. We look forward to staying again the next time we are in wonderful Buenos Aires.
