The check-in time is very flexible and Joaquin, Carlos and Natalia were good with communication. Me and my friend did not have any trouble and even they prepared our room much earlier than our check-in time! The apartment was super clean and spacious (it was new?) and has an elevator as well. He provided the city map and gave us various tips on restaurants, shopping streets, and famous building etc... Also, the apartment has a travel booklet with full of information. Me and my friend enjoyed our stay without any problem. I will definitely go back to their apartment in the future.
