We stayed at Mario's place our last nights of a multi week trip with our 10 month old baby. It was really great overall - the crib was perfect for the baby (it stripped down to just a fitted sheet) plus there were tons of toys that he was super excited to play with, paired with a long hallway to crawl up and down. The living room isn't child proofed, which wasn't a problem for us, but may be worth noting. The apartment was bright despite having only internal/air shaft windows. We never met Mario, but he was very nice and always super quick to respond over message - checking in with the doorman was very easy. The neighborhood was walkable and relatively central, and definitely a bit of a party area - which may or may not be exactly what you're looking for! Overall a good experience.
