I would highly recommend this apartment! It is in a great neighbourhood with lots of cafes, restaurants, bars and nice little shops. The station Trindade with a direct tram to and from the airport is only a 5 minute walk from the apartment. There are ACs in the apartment but we never had to use them (despite outside temperature of over 30C) since it was never too hot in the apartment.
The communication and check-in process with Daniel was very smooth.
