Sebastian was very prompt with his communication with us. Maria was waiting for us at the apartment even though it was 12:30 am when we checked in. She gave us extremely detailed tips and suggestions about local places to go to. She also helped us to leave our bags in the building even after check out time even though this was New Year's Eve and she had plans. She insisted on giving us company until we take a cab (the airport taxi which she called for us that accepts credit card payments) to the airport because it would make her feel better to see us off which worked out for us since we were not able to find an Uber and we did not have enough cash left for a regular cab. Once the trip was done, Sebastian contacted us to make sure our trip back was fine.
The location of the place is excellent. Everything that is touristy is in walkable distance from their place.
I would defintely recommend this place to everyone!
