Sergio was very helpful; the check in process was very easy as Sergio met with us to hand us the keys and go through the details with us. The keys were numbered based on the order of doors to open and that was a great touch. Sergio was also very quick to respond anytime we had issues or questions. In addition he gave us great local tips which were very very helpful. The apartment was very clean, and is a central location to many tourist spots; being close to the metro station was very convenient. I would highly recommend this place
