I traveled by myself and felt very safe and comfortable in Astrid's apartment. The space is definitely big enough for a couple though. The apartment was decorated warmly and has everything you would expect in an efficiency. Astrid also left some nice personal touches in the apartment that made for a nice arrival (e.g., sparkling wine, fresh eggs)! Also, she was very responsive to any of my questions/concerns during my stay - everything went very smoothly. Thanks again, and I hope to visit again soon! Auf wiedersehen :)
