We had a great stay at Martin´s place. It was a perfect stay with a toddler. The Schönbrunn was just five mins walk and you have a big park and a playground area in few mins walk. The pictures don't do justice to the apartment, its actually even bigger and very cozy. There is a tram station just around the corner and a bus station in front of the apartment.
Unfortunately few things, just as, coffee machine and hair dryer were missing. So if you want to have coffee in the morning, make sure to ask in the beginning, if it's available. Other than that it was a nice stay, we would recommend Martin place 100 %.
Thank You for hosting us.
