We spent one week here, using Liberec as a base for exploring the city, hiking in the mountains around it, and visiting nearby cities and sites as well. We booked one of the so-called designer room, which I highly recommend. Our corner room was spacious and quiet. Views from the hotel are not spectacular.
Service, however, was another thing. Many of the hotel stuff we came across were defensive and not willing to help. There was something very rigid in the type of responses we got (usually a "no"), and even positive responses were given reluctantly. Are local calls made from the room free? "yes." Ask the same question the following day, and it is "no". Can someone help us book a spa appointment in Czech? "no, that should speak English at the spa." Of course they didn't - we tried. Unhelpful and curt - that's the reception for you.
Room cleaning was another issue: during our one week stay, amenities were never replenished (we bought our own soap), carpet never vacuumed, and we found out that the wine and water glasses were cleaned in the bathroom sink, not replaced with fresh ones. Poor customer service.
Breakfast was the same every morning. Vegetarians beware - it's all about meat here. Vegans - forget about it. The first morning I dared ask for an omelet - the evil looks I received were enough to dissuade me from asking for anything special in subsequent mornings.
