Dan's apt is located in a very convenient area - 5 min walk from schwedenplatz U1 metro stop. Very convenient to get all attractions.
Pros: very convenient location, clean, large comfortable bed
Cons: small space - living space approx 13'-18' (there's a king bed, end tables, sofa bed, tv with stand, clothing racks and a small table all in that space), no circulation (although we were there when it was very hot - one fan in unit). Apt is located on ground floor, can be noisy in mornings with bikes and trash being moved around as unit faces interior garden.
Overall, I'd recommend the apt for light travelers that don't require a lot.
