Good hotel, improvable breakfast

I felt quite comfortable in the hotel. Everything is fine but I was missing some things in the breakfast that are available in any buffet of any hotel, for example bacon, ham, ... the nuts need to be changed once in a while, I took some pistaccios and they were so soft, probably too old

The hotel is beautifully situated close to the heart of Sønderborg, offering stunning views of the harbor and easy access to local attractions. The rooms are spacious and modern. As we traveled with our small dog, we incurred additional cleaning fees of 300 DKK per night, which is approximately 40 euros. We have stayed in many European hotels and have always paid between 8-15 euros max; therefore, the price is simply exorbitant. It was all the more annoying that, whenever we left the room with our dog, we informed the reception that the room service could come to clean. Unfortunately, this never worked directly, so our room was only cleaned during day trips every second day. In addition, it was inconvenient to always have to leave the wet food for the dog at the reception because of a missing minibar at the room; the staff helpful. Our room had a breathtaking view of the sea, which was a nice sight to wake up to each morning. Steigenberger has an array of nice amenities. Great is the Spa area; still, for the overall price we paid for two weeks it was a pity that the access to the pool was not included. Additionally, we were somewhat bothered that, on top of the 'normal' spa area costs, there are additional charges for the Nordic Spa area. For a hotel in this price range, a spa area should naturally be included in the overnight price. The dining experience at Steigenberger Alsik is very good and we would like to highlight the extraordinary breakfast buffet.

Det var utrolig flotte værelser. Boblebadet var lidt i stykker, virkede som om mosaikkerne var blevet ødelagt af vanddysserne. Jeg kunne godthave haft poolen 1-2 grader varmere men det er jo en smagssag. Ellers var det helt perfekt.

Super hotel med skøn morgenmadsbuffet

Rigtig god oplevelse og super service af personale i reception og ved morgenmads buffet. Vi fik dog ikke tilbudt opgradering til et værelse med bedre udsigt og heller ingen info om faciliteter v ankomst og tjek in. Dårligt at der ikke var ledige tider til massage. Det kunne også have været en super service at vi fik tilbudt bestilling af behandlinger efter booking af ophold, så vi kunne booke på forhånd. Der manglede conditioner og body lotion🙁 Hotellet ligger centralt og ved havn, så det er nemt at gå ud og opleve dejlige Sønderborg by.
