I stayed at Carolina's apartment for 3 nights (I had to leave a day earlier) and had a great time there. Carolina sadly was traveling at the same time, but she arranged for her business partner to receive me at the apartment and made sure that I had everything that I needed. The apartment is lovely, in a cute building (with lots of character) and at a great location. Metro station is literally one and a half blocks away (15 minutes from the airport), the neighborhood has a great vibe and energy, and I was able to walk everywhere form there.
