We stayed at Martins for 4 nights. It was wonderful. While it is very definitely a summer home, it was comfortable and had all the amenities you would need. We were happy to find out that it is only about 30 minutes to downtown Stockholm by train,and the train station is only about 10-15 minutes away by car. There is also a bus to the train station. You can get downtown for about 3EUR and the trains come ever 15 minutes pretty much all day. Parking at the train station is free. For us it was the best of both worlds, beautiful peaceful countryside and close enough to go into the city easily. We even saw a mother and baby moose!
The bedrooms are small, but the beds and bedding are very comfortable. There is a fire place, and plenty of wood provided, which was great. The kitchen was well equipped having ample pots, pans, strainers, peelers, etc And you could dine inside or outside. There were a few grocery stores near the train station (so about 10 minute drive) and a huge grocery store about 20 minutes away by car.
Check in and check out were easy, and our GPS even knew where the address was- a huge plus! Martin answered any questions promptly and even left us some treats as a welcome gift!
I would definitely highly recommend.
