Location: Great Location. Beach, Grocery stores, pharmacies, restaurants and bakeries, banks, atms, and currency exchange, hookah lounge, bars and night clubs are all within walking distance of apartment.
Cleanliness: apartment was spotless. Very clean linen and towels. Clean furniture.
Comfortability: apartment is very nicely designed. Not much room to move around in the kithen and bathroom. It was hard to maintain consistent warm water in the shower. Maybe it was operator error. The full size mattress bed was not very comfortable and it is very low to the floor. But then again i am use to huge American mattresses in USA. Bedroom has a single pane window facing Copacabana Ave. You can hear everything from outside. Consider bringing ear plugs for a better night sleep.
Safety: 24hr door man that has to buzz you in to the building. Very safe area in my opinion.
Transportation: uber is definitely cheaper than taxis. But either option is very easy to access as well as buses.
Amenities: Kitchen was well stocked with plates, cups, and utensils. Wifi worked great. AC worked great.
