Heloise was easy to communicate with and to reach before and during our stay, which was very much appreciated. The apartment is nice for 2-3 people. It feels safe and private, down a long common corridor lined with plants and open to the sky. The neighbors whom we encountered were friendly.
We stayed for 16 days and were especially happy with the location because we have friends who live in the area. There is grocery store within one block, plenty of restaurants, and the bike lane is right out in front. The unit is bright because there are a number of windows and a skylight. The bed was quite comfortable, but the bed linens has seen better days and the pillows were unacceptable. The shower posed a problem because the water temperature would not stay fixed. The water does not warm up unless you set the valve to the hottest setting. It then warms up to the point of being unbearably hot and if you try to adjust it, it gets cold almost immediately. In contrast, the kitchen faucet, when turned to hot produced scalding hot water. Fortunately, it can be turned down to a comfortable setting.
The WIFI was fast (for Buenos Aires) and the A/C worked well. Overall, the apartment is a good value. The answer to the most common question (would we return?), is yes.
