Andrea and Tomas were absolutely fantastic hosts. They were quick to respond every step of the way, and helped us find nice things to do with our kid.
Regarding being a non-kid-friendly apartment, it really depends on the child. There's a pretty high ladder to a small mezzanine that thas no fence for safety, and an easy-to-open window low next to the bed with a big drop outside. We had no problem managing these hazards, but the warning is in the description for a good reason. The ladder was even a fun playground-like feature when used properly :)
