My brother and I stayed in Fernando's apartment for 10 days in August of 2014. We both had a fabulous time in Buenos Aires, apt was close in proximity to the subway, bus stops & cabs aplenty. The apt was a studio size with a cute balcony, roof access, laundry-easy to handle.
The entry door to the building is double-gated entry; loved that.
The only thing that I would perhaps comment about would be the location. The Ad states that the apt is in Palermo. It's actually in Almagro. I've checked approximately 5 maps
to be clear on the area but it is indeed Almagro and not Palermo proper. It's very close to Palermo which is nice being that we would dine there on most nights.
Affordable, safe & quaint apartment in Almagro about 8-12 blocks from Palermo.
We dealt with Andrès who also managed the apt we rented. Very kind man we saw but a few times. Positive experience overall.
