If you're a single or couple looking for a great value for a place to stay in Copacabana, I don't know how you could do much better than Dalia's place.
The location is superb. Take the elevator downstairs, leave the key with the 24 hour doorman, walk out the door and cross the street and you are on world-famous Copacabana beach.
The room is comfortable, there is a nice little view of the beach from the window, and some great dining and beverage places on the same block.
But what separates this rental from many others is Dalia's hospitality and kindness. You'll not find a sweeter hostess. She advised on anything and everything I could think of... had lots of sweet touches in the room like fruit and sweets when I arrived... and overall was a great friend.
You can't go wrong with Dalia's place.
