We stayed in Markus' large flat for a week of work with our 5 month old and grandparents in tow. The flat is spacious and well lit. Markus had a pack-and-play that he kindly set up for us as well. The location is great for kids and adults. The nearby Delores park is a great place for a stroll, and has a fantastic playground. The well-known Tartine bakery, a block away, provides sustenance for the adults, as does nearby Delfina restaurant.
