The location is exceptional. You're in the heart of Recoleta, close to everything (small grocery store downstairs, a supermarket half a block away, a mall a few blocks away...and I can go on and on)
Safety was a big deal for us and we felt beyond safe staying at German's place (the building also has a doorman/maintenance guy most of the day).
The apartment is very spacious and has a lot of plus items that make life easier we didn't have while staying at another place in Buenos Aires for a similar cost (washer, iron, hairdryer, international plug adapters, electric kettle, basic kitchen things when you first arrive such as salt, sugar, tea, oil, etc...).
German greeted us and was very helpful regarding a few questions we had - communication during the stay was smooth.
Overall a great experience and will certainly try to book it again once back in Buenos Aires!
