As everyone else has noted hotel is very convenient to main train station. Large depot for bus and tram travel is also very short distance, so access to nearly anywhere is no problem. We also got train to Frankfurt airport which was very handy as didn't have to walk quite a few blocks with bags in tow to get to the hotel pick up for the airport shuttle bus. With 2 young children we had no problems walking into town also. Internet located in reception was very handy. During our stay there was a strike of airline employees in Frankfurt and hotel staff assisted us in trying to get information. When sending an international fax reception staff were also very patient and helpful. We were a party of 5 and had 2 rooms. I stayed with our 2 children initially in the one bed, then improvised the second night with chair cushion and an extra pillow from reception. Rooms are ok size, however storage was a little tight with 2 suitcases. Very happy with price, and considering only a 2 night stay, happy overall.
Small but satisfactory rooms, well placed for walking into the old town, good, safe, free car parking at rear of hotel, excellent staff. This is a university and tourist town - the Ibis provides good value for money. The breakfast was expensive but better value than the station restaurant next door. You will find plenty of good restaurants within easy walking distance in the old quarter. A short stroll from the castle and old city, surprisingly little traffic noise.
Ibis Heidelberg, actually there is not much to say it is the average Ibis Hotel. It is a clean hotel but the bathrooms are very tiny. Two average people do not fit inside together. I am not sure about the breakfast, I did not take it, but it is € 10. The Hotel is located right by the Heidelberg main railway station but to go downtown it takes a 5 station tram ride or the bus. Day-Tickets for the Heidelberg public transit system are about €5 for one person or €9,60 for a maximum of 5 people.
I can't believe the negative comments about this hotel, especially the comments about room size (largely from American reviewers). This hotel is slap-bang next to the train station and yes, if you leave your windows open you can hear the female train announcer, but I loved to do this, as I also loved to hear the German trains in all their varieties coming in and out. It's like being in your own version of a WWII escape film. Shut the window and you can't hear anything.
The breakfasts here were excellent, as they are at every Ibis I've stayed in .The beds are comfortable, the bathroom ain't massive, but it's good and the hotel is scrupulously clean. The A/C was great and the staff were routinely courteous and helpful. I'd recommend it to anyone.
We stayed in a smoking room - Ibis Germany always provide these.
The downside of this hotel is not the hotel's fault: it is a ten minute tram ride from the Altstadt. I wouldn't bother trying to walk it. But none of the hotels in Altstadt looked worth the 200 quid a room/night you'd pay. But then again, Heidelberg was disappointing itself.
Perhaps we just weren't used to a European hotel... this had the tiniest room and bathroom for a hotel that I've ever seen. There literally wasn't room between the foot of the two (twin size) beds in the double room to roll the suitcase through to the far side of the room. Was certainly satisfactory in terms of cleanliness and access to the main train station (next door). For someone who just needed a place to stop, drop, rest, and freshen up prior to a flight, was adequate. The dining area was nice.
