Really large quadruple rooms, even for a family with two kids. Valuable breakfast, with a good variety. The staff was extremely kind and prepared about the local area. Some details were warmly appreciated (cold water, still and sparkling, for free in the minifridge; room slippers and even bathing gowns provided for free; selection of teas and infusions; big screen flat tv with Sky channels). The position is ideal if you want to visit Heidelberg (it's just an easy 10 minutes drive). Around the hotel you find a sportscentre, and many biking and walking/running trails.
The hotel is not signalled, and the locals seem not to know exactly where it lies, so if you are not using a navigator, you can easily spend some minutes driving through the little town of Leimen in search of it. We stayed at this hotel twice in a 2 week span, in 2 different rooms. The first time (middle of August), our room was extremely hot, and sleeping was difficult. There is no air conditioning, just an air fan that was totally inadequate to refresh the room. Wifi connection was so slow and unreliable, that it was impossible to navigate or send emails, and we tried at different hours, even early in the morning. It was barely enough to use WhatsApp or similar apps. On the contrary, in the breakfast room it worked perfectly.
The second time (end of August), our room was much fresher, and we slept very well. The wifi connection worked outstandingly, easy to launch and very quick.
