Helpful staff at this hotel always willing to help and advise. I was in room 26 in the annex which was not directly accessible by lift so had to carry my case up a flight of stairs. There is a lift to the 1st floor however, from the main building, and you then need to cross the walkway to get to the annex. The good thing is that there are only three floors in the annex. The room was large and spacious, as was the bathroom. The walls are quite thin as I could hear next door's shower and bath running, so a peaceful night's sleep was not had. Bedding was a bit strange too - with the duvet in the cupboard and a narrow bedspread across the centre of the bed - so I basically had to make my bed! There was no shower screen/curtain will led to a very wet floor.
The rooms in the annex have an outdoor area for each room, for room 26 this was quite a large decked space, and a nice surprise, in which to relax.
It is out of the way from the centre, a 31 mins walk, but is definitely walkable. I'm m not quite sure how this is a 4-star hotel though as there is no restaurant and no room service after breakfast. There are a few restaurants nearby, but these tended to be Asian restaurants or traditional Czech pubs. Lavande is a nice restaurant and a 10-mins walk away.
