We (2 adults + 2 kids (9y and 3y)) stayed for 4 weeks. Location was perfect for kids, big playground just outside and walking distance to park and central station. The neighbors where not used to kids and the noise they make, so there was a complaint. This is not a problem when the weather is nice, but it makes it difficult to stay inside on rainy days.
Richard was very accommodating to our needs for flexible checkin and was kind enough to invite us to his garden house where the kids picked lettuce and herbs.
The apartment gets very warm when the sun is shining and it is difficult to cool it down.
