A great location, warm place, enough space, Greta is a responsive and caring host. We haven't met her in person but the communication was smooth before and throughout the stay. There is a baby crib and a feeding chair available at the apartment.
Non-critical issues: it is not 100% non-smoking place as you may feel that somebody smoked in the apartment before, though the smell is not very intensive. There are no blackout curtains in the bedrooms, so if your kids are used to sleep their day sleep in a dark environment, it might be a bit challenging there. Also, the floors are squeaky at the apartment and at the apartment above, so some noise might be at night when neighbors are walking there.
Overall, it was a perfect stay at a nice place :)
