This hotel is, by far, the best in Sarajevo. Perfectly located in the heart of the city--close to both the Old Town & city center for those traveling for pleasure, as well as all the main administrative districts for those traveling for business--the staff is by far the friendliest I've experienced in any hotel in Sarajevo (note: even more so than its competitors, i.e. the pricier Swissotel and others, where the service makes the experience decidedly less than 5-star).
The staff are friendly and more than willing to go out of their way to accommodate guests in any way they can, which really means a lot for people on a short business trip in particular! Furthermore, the hotel itself is beautiful--the lobby and the cafes in particular--, the food is delicious (try the Bey's soup in the restaurant and the "medena torta"/honey cake in the cafe), and the spa is well-equipped and the perfect size for some quick and quiet relaxation.
Overall, an amazing hotel and my absolute favorite in Sarajevo!
