I think this was the best Airbnb I have ever stayed in, and I travel a lot. I even extended my stay for one week in Buenos Aires just to enjoy it. The flat is huge: with a lot of light and extremely tall ceilings which gives an incredible feeling of space. It is conveniently located close to the Subte line C plus it is a just 5-minute walk from San Telmo market where you can find fresh produce and artisan bread (which is hard in BA!). The art moderne interior is thoroughly thought through: the eye is pleased wherever it looks. And I must say it is much better in life than in the pictures. There is everything you need in the apartment: a lot of storage space, nice selections of books, the kitchen is overly equipped (which you would appreciate if you like cooking like me!), a separate working cabinet, and a room where you can watch movies.
The check-in and the check-out process were smooth. There is a doorman in the building and you can always ask him a question. Moreover, the host - Stephen - was very attentive during the stay constantly checking if I needed anything.
I look forward to coming back to Buenos Aires and hopefully staying in the apartment again.
