Isabel was a great host, who communicated really well, and we had no trouble getting into the apartment even though our flight was delayed and we got in late on a Friday night. She was also very accommodating with our late departing flight on our departure day, much appreciated.
The apartment location is fantastic - only a few minutes from the castle (great for a sunset) and very walkable to the city centre. The drawback of being so close to the city is the very noisy tram line that runs directly under the main room and master bedroom - bring earplugs!
The bathrooms and bedrooms are all fairly basic, but perfectly clean, and the beds were comfortable. The main room is small and the sofa/rug could do with a thorough clean - but perfectly serviceable. The kitchen is also small and only had stools to sit on, not proper chairs, but as we didn't really use it for more than breakfast this wasn't a problem.

I would recommend the apartment as the location is unbeatable - thank you to Isabel for being such a good host!
