MY wife and I had stayed 5 days at Per-Marten's lovely apartment in early June 2012. The apartment is just like in the pictures and description. It is very clean and well kept and Per-Marten had been a great host, giving us great recommendations and being available for questions we had during the stay. We would definitely recommend this place for friends and family and hope to some day come back!
(BTW - the location is great, just off the subway, with many great restaurants nearby. It's also pretty close to everything and with a few minutes walk would get you to most places).
