The apartment is excellent, well equiped and well located, in the heart of Recoleta. We've did several things just walking, and for far places, it was easy to take a taxi or use the subway. There are good convenience centers around: supermarket and laundry (1/2 block), drugstore (1 block) and restaurants. It's close to 2 big avenues (Santa Fe and Pueyrredon) with many stores and restaurants. There is a washing machine on the last floor, but we've used a laundry 20 meters from building (Lucas's suggestion). For only 32 pesos you can wash and dry all your clothes. The owner is gentle brazilian girl called Daniela.
The apartment is exactly the same as showed on the pictures. It was clean and organized when we arrived. The neighborhood is very nice. We've stayed for 1 week and Lucas was a great host. We could contact him by whatsapp anytime, and he promptely answered our questions. We were received by Lucas, who gave us the keys and explained to us the basics of the apartment. I recommend this apartment for everyone, and I would stay again in a new trip to Bs.As.
