Overall the experience was ok, the apartment is roomy and renovated very recently, in a very central part of Buenos Aires (super close to all the metros and good neighborhood, close to San Telmo). However we did not feel listened to. We asked some questions that were left unanswered and we pointed out some flaws in the apartment and did not get a response either...
Some things can be easily improved to make it a really great place to stay, hope it will be done for future guests!
