We loved our month in Marcela's apartment! It is as lovely and clean as pictured. Marcela is a kind, thoughtful and responsive host. When we arrived, she met us and gave us all the information we needed, showing us the laundry room., etc. and even left fresh fruit, chocolate and a bottle of Argentinian wine. She is very knowledgeable about the city, of course, and has guidebooks and maps in the apartment. If we had any questions, we could send a note and she responded immediately. Very thoughtful.
The bed was very comfortable, very nice linens and towels, and a large ensuite bath with tub and fabulously strong shower. The kitchen had everything you would need to cook, and shops very nearby with large grocery store just a few blocks away. We enjoyed the location just 2 short blocks from a subway station. Note for longer stays like ours you can purchase "Subte" cards and load them at lotteri stores for use on all public transport. It is also a great location to walk around and see Recoleta cemetery just 2 blocks away, the fine arts museum (free, and very nice) and many parks nearby. Also plenty of restaurants are close. The wifi was strong and pretty reliable, the tv was great, and the apartment is decorated with nice original artwork. Beautiful.
We would love to stay again if we are ever in Buenos Aires. It even has a rooftop pool good for summer months (too cool while we were there). The location was perfect for us!
