My place is good for couples and solo adventurers. There is both a big loft-bed an a large sofa, two persons can sleep separately. You will have access to the kitchen, bathroom and the living room. Since I am not asking for a cleaning fee, I would request that the guest(s) cleans up the place before leaving.
Everything one must see in Heidelberg is within walking distance. You will not need to use public transport to see sights, or to do shopping. There are two markets each 100 meters away to the right and to the left when you go out of the building into the main street. All the cafes, shops, pubs and tourist destinations are reachable at most in five minutes by foot.
The apartment is in an old classical building, with high ceilings and wooden floor.
Kitchen, bathroom, living room.
I will not be in Heidelberg, but am always available by email or phone.
There is no curfew since you will have your own key, but being moderately silent during nights is expected.
