The property is nicely located near the river and close to Hrad Devin. It's a wonderful walk and the old castle is cool to visit. It's a 45 min public transit to get to Bratislava if you want to see the city. The directions to the camp site could use some work, so I'll put them here, but the owner was very responsive walked me through getting to the campsite. Bring mosquito repellant.
Directions:
The pin provided is a bus stop. From there, walk towards Bratislava until you see a white mailbox with a Camp sticker. Get the keys from inside the mailbox. Walk up the stairs until you see a green gate, which is occasionally locked. Go through the gate - if locked use the key. The property is the second cottage on the left.
