We (me, my wife and two kids, 8 and 6, stayed at Pablo's place for five nights in December 2018. The apartment is in the Palermo neighborhood, 5-minute walk from the Palermo metro station and 10-15 minute walk from Plaza Serrano, an area with many restaurants and shops.
The place was exactly as we expected it to be from the photos and Pablo was an excellent host. We arrived in Buenos Aires a bit earlier than the 2pm checkin time and Pablo was very accommodating in letting us check in early and made sure we had everything we needed. If back in Buenos Aires, I would stay in this apartment again.
