I planned to stay there for 3 nights but had to leave after the first night due to the noise at night. People were partying in the streets until 4 am and unless you are a very sound sleeper or a party animal yourself I would not recommend staying there. Rooms facing the courtyard are supposed to be quieter, but you can still here people coming and going in the hotel. At 6 am the noise started again inside and outside the hotel.
The room itself was very cosy, had a flatscreen TV, telephone, and internet access. The bathroom, if you could call it that, was more like a bathroom cubicle, very tiny and smelled like mold.
The food in the restaurant is excellent and breakfast was average. Personnel is very friendly and accommodating.

Amazing food, perfect room, helpful staff, wonderful stay! Fairytail like village and hotel. Some of the best food we had in Germant came from this little gem and it is a MUST to eat here, you will be missing out if not.. We had a great stay and woulf forsure stay again.

We stayed at the Hackteufel for a total of about 10 days in December. My husband, 18-year-old daughter and I were in Heidelberg to visit our son, who is studying there at the University this semester. Perfectly located in the heart of the Altstadt, a half block from the Alte Brucke (Old Bridge), the Hackteufel was a friendly, comfortable place to come home to after a day of sightseeing and shopping. The staff could not have been more welcoming and hospitable. The restaurant is wonderful--and popular among the locals, which tells you something. We enjoyed our breakfast there each day and also had dinner there a few times. The apple streudel is to die for! The only downside to the Hackteufel is that on weekend nights, streetside rooms are rather noisy. On our last visit to Heidelberg (several years ago), we stayed at der Europischer Hof, which is very posh, but a lot more expensive and not as well located. We would gladly return to the friendly, family-style Hackteufel if we have the chance!

For our one-night stay, we were given the room "under the sky" (room 12), which had a beautiful view of the Heidelberg rooftops and the castle. The atmosphere was perfect for a romantic getaway---from the gabled and beamed ceilings to the spacious bed---and the location is perfect--less than a minute from the Weinachtsmarkt, and only minutes from almost every other site worth visiting. My recommendation---try the pumpkin soup at the Hotel restaurant! It was one of the culinary highlights of our brief stay in Heidelberg. My only regret? Not having another two or three days at Hackteufel!
