Christian's place is very clean and has all of the basic necessities for your trip. They were very accommodating and provided great recommendations. The building itself had unique and cool style which we enjoyed!
*I will note that if you are light sleeper keep in mind that the flat is in the corner of the building which is on a corner of a pretty busy street which can be noisy. However it is a great location, walking distance to every major part of the city and right across the street from great food. Just around the corner are some delicious local tacos; you'll know it when you see it because there is a never ending crowd around their window.
