Janu was very responsive in the weeks before our trip, answering all of my questions. He was a gracious host who was home when we arrived (he lives in a building on the property) and made sure we had everything we needed.
We had a party of 10, including a 70 year old, 21 year old, (2) 11 year olds, and an infant and everyone had their space and things to do in the house. We especially loved watching our kids play with Janu's son on the trampoline and enjoyed having them over for dinner. It was a great stay. The neighborhood is very nice and only about a 12 minute subway ride into Stockholm. The walk to the subway station itself was about 10 minutes, which was fine for everyone except my frail mother. If you have elderly folks with you, please keep that in mind. Overall, the house is large, 60s/70s chic, and a ton of fun. We were all very impressed.
