Actually I stayed in 'happy house' which I can highly recommend to everybody who enjoys meeting other people, mainly students from Southern and Central america. The house is lovely, reasonable cool even during heatwave days with a nice rooftopterrace, well equipped kitchen, enough (2) bathrooms on every floor. Above all the house is kept pristine clean. Erna as your airbnb hostess is an infinite source of information about the area and to make communication even easier: Erna speaks many languages fluently. 'Happy house' is located in a lively area though on a quiet side street. Don't hesitate when there is a room available!
