My husband and I stayed in Carolina place for a week and it was perfect for us: a cosy apt in a calm neighborhood and away from the tourist crowds, but with easy access to the metro. The kitchen has everything you need and more.
The apt is located in a nice building on the top of a hill, and has a nice balcony facing the Waldorf Astoria Hotel where there's a taxi stop if needed. But if you're not willing to exercise your legs or use a taxi, you can easily catch the 913 bus that stops at a 5-minute walk distance and goes to the metro. The bus stop is conveniently in front of a supermarket.
But no worriers, Carolina will explain you all that. She is a wonderful host!
