We tried Airbnb for the first time and it turned out great! Egle's appartment was not only clean but beautifully decorated. I have to admit that We thought it was going to be a bit small, but it turned out to be quite ample in space. Also, everything, from shower to frifge seemed quite new.
The appartment was also conveniently located close to a groceries shop, drycleaners, the neighbourhood café, couple of nice restaurants, butcher shop, and even a wine & cheese shop. It is not close to the "microcentro" (about 45 minute walk), but a "subte" station is only a couple of blocks away and taxis are easy to find and are inexpensive. As a reference, the taxi to downtown costs about AR$30.- (about U$7.-). We walked to downtown more that once, and it is a nice walk if you are not in a hurry, specially because in the way you pass by the palace of congress, avenida mayo, casa rosada, etc.
The neighbourhood itself was quite relaxed. After a couple of days we started chatting with locals who gave us plenty of tips and conversation.
The host was extremely nice and gave us plenty of tips too.
If you are looking for a laid back area of Buenos Aires to stay, I very much recommend Egle's flat!
The only thing I regret is not having spent more days there!
