Just got back from a weeks stay in Carlos apartment and it was just like the pictures. Good space for 4 people. Very safe neighborhood never felt unsafe as we went out every night and came in later/early morning. Very quite building with great Cafe on the grown floor that is great for breakfast or a cup of coffee. The 2 beds were both comfortable, but only the bigger bedroom has a tv in it along with the tv in the living room. Very close to Copacabana beach, less that a 5 minute walk and 10 minute walk to Ipanema beach, both are very nice beach. Great restaurants within walking distance of the apartment, just walk in any direction and you will run into something worth trying. Very easy to grab a cab at the corner and about a 35-45 minute cab ride to the International airport depending on traffic.
Upon checking in Fernanda was there waiting with the keys, we got in early so Carlos let us check-in earlier for a small fee, but worth it since most flights from the United States get in really early and we also paid for late check-out since our flight didn't leave until later in the evening. Fernanda does speak English so we did our best to communicate what I needed to understand about the apartment. Carlos check-in with me halfway through the week to ask if I needed anything and I thought that was very helpful. The building is secured with a doorman at the front desk.
I would recommend this place, great location for first time people to Brazil.
