I couldn't be happier with my stay at Sara's place! The building is perfectly located on a quiet street in Palermo Hollywood, within walking distance of all the bars and restaurants of the area, as well as of the Ministro Carranza station of the subway line D. You can also take bus 39 to get around. The area is safe and good for running as well.
The building is very, very nice, with a huge pool and sun deck on the ground floor. Most pools in this area are not very big, so this was awesome. You can swim and sunbathe and it was never too crowded. On the 10th floor, there is a really nice gym as well as an indoor pool which would be great in the colder months. Everything is sparkling clean. The security people were always very nice.
The apartment itself is nice and big, with a combined living room/kitchen (two people can sleep on the pull-out sofa here), beautiful balcony (so peaceful!), a large bedroom and a bathroom with everything you need. Sara provides towels and linens and in the kitchen, the cabinets were stocked with essentials such as salt and pepper, oil, coffee, tea, sugar, mate - really convenient! The fridge is full-size and Sara had thoughtfully left a big bottle of water there. Plates, bowls, glasses and silver ware for six made it easy to prepare meals there. There is AC both in the kitchen/living room and the bedroom and it worked perfectly. If you want to watch TV, there are lots of channels and two TVs.
I loved my four days at Sara's apartment and did not want to leave! Everything was great but I think what particularly stood out was the location, how quiet the street is (a HUGE bonus in a noisy city like BsAs; made it easy to sleep!), the balcony, and how complete, well-stocked and well-functioning the apartment is. Oh, and of course Sara's helpfulness; she answered all my questions beforehand and was always ready to answer questions during the stay - although I didn't really have any because she had explained everything so well.
I very much recommend this apartment and the building to anyone visiting Buenos Aires.
