Hmmm, boring and no soul

Hmmm, what to say - expectations were rather moderate, we did however arrive and with a version of expectations to be meet with a smile. Alsik as a hotel is for the guest who wants cold, simple & conference look alike. We are more in thw mindset of quality rather than quantity, we cannot recommend as it lacks personality and service minded staf.

We stayed for two nights over New Year’s Eve at the Alsik Spa Hotel, and overall we were very impressed with our stay. The hotel itself is beautiful, modern, and extremely clean. From the moment we arrived, the staff at the reception were very friendly and welcoming. We had booked a Junior Suite with breakfast on the 8th floor, and it exceeded our expectations. The room was spacious, stylish, and impeccably maintained, and the view was fantastic – especially over New Year’s Eve, which made the stay even more special. Breakfast was excellent, and the overall service, room quality, and hotel atmosphere were outstanding. We would absolutely love to return. The only real downside was the spa area. Even as hotel guests, access to the spa comes at an additional cost, which is quite high. Although hotel guests pay less than external visitors, a 3-hour spa slot costs over €40 per person, which is not insignificant. The spa itself is clean, modern, and very well equipped, so there is nothing to complain about in terms of facilities. However, at this price point, one naturally expects excellent service and hospitality. Unfortunately, this is where our experience fell short. Some of the spa staff appeared unorganized and not particularly friendly, at times even a bit condescending. For example, after our spa visit, we simply asked for a fresh bathrobe to use in our room, as the spa bathrobe was completely soaked. Initially, we were told this would be charged extra, which we found ver

Helt forrygende. Værelset står helt perfekt. Der er sket meget nyt og godt på Alsik - det er så tydelig at der er kommet stærke kræfter på F&B. Imponerende ro under morgenmad med fyldt hotel. Dejlige nye arealer i forlængelse af lobby og den nye bar er et rigtig godt tiltag. Vi kommer snart igen.

Vær opmærksom på at selvom man betaler Premium pris for en Suite, kan man ikke så meget som at tage en svømmetur uden at skulle betale for det! Al adgang til spa og swimmingpool skal bookes i forvejen på bestemte tidspunkter og er relativt dyrt. Middag i restauranten: maden blev hurtigt serveret, men så var det som om betjeningen glemte os. Så tallerkenerne blev aldrig ryddet ud og vi blev aldrig spurgt om vi ville have dessert eller kaffe. Efter 30 min. gik vi op og betalte. Morgenmadsrestauranten var et rent kaos. Der blev ved med at være tomt på buffeten af essentielle madvarer. Nu er det 2. gang jeg overnatter der. Første gang var kort efter åbningen, og der levede de ikke op til forventningerne. De fik en chance mere, men nu kommer jeg ikke igen. Så jeg kan ikke anbefale det til andre.
