My wife and I stayed at Pansion Harmony September 5-8. Before the trip, we learned that we needed to add a day to our stay; the website showed that our class of room was not available for the extra day, but we e-mailed the hotel, and the owner arranged the extra day for us. The hotel is high on a hill and the view is beautiful, day or night. We were greeted upon our arrival, and made to feel very welcome throughout our stay. Our room was attractive, spotless, comfortable, and a class above what we reserved. Breakfast was great - plenty of choices, well prepared, and the breakfast room was very pleasant.
The ONLY drawback to this hotel is that is a 15 minute cab ride to downtown and back. The owner called a cab for us every day and they arrived promptly, and you can catch a cab from the taxi stand downtown. (The fare should be around 4 Euros. Confirm the fare before you get in at the taxi stand; one cabbie took a very creative route back to the hotel.) But some days, it would have been nice to just duck into a dowtown hotel in late afternoon to rest up and wash up for dinner, which isn't really an option this far out of town.
Overall, I would highly recommend this hotel, and Sarajevo as a tourist destination, to others!
