We had a great experience at Wilken and Elio's apartment. The flat is extremely well located, and taxis are easy to come by. The apartment is spacious and comfortable - exactly as pictured in the photos. Wilken and Elio were also extremely helpful and allowed us to check in early and checkout late!
The one note I would make is that there is one shower - this didn't bother us at all and the shower worked very well (we were 7 girls), but worth noting :)
