Pros: Best location in Buenos Aires, everything is close by. The apartment also is excellent. it's tidy, spacious, good heat & AC, and the house has a cool rooftop.
Cons: Unfortunately Emanuel had told me a wrong address so I walked through half Palermo with false information. After going to a restaurant to get internet and contact him I waited over an hour for him to come bye, not willing to give his phone number or to call me, which made me very insecure whether he would show up at all (after a non-existing address and having to wait for so long + no phone call I wasn't sure whether it would work out at all to be honest). After finally showing up he apologized many times and proposed to invite me to dinner. I'm confident he will improve these errors for future guests. He generally tries to be very helpful and he is very concerned that the guest feels well (for me personally a bit too concerned - he texted me during my stay that he was worried after I hadn't responded for 11 hours overnight). He will offer you a lot of help and ask to hang out. I think he would be a good host though for people that are looking for things to do and are new in town and want company.
Despite the bumpy road at the beginning I would stay again!
