Great Little Hotel
The hotel is NOT in city centre, but if location is not a priority, it is a truly fun place to stay. Staff are terrific!! Friendly and efficient. Enjoyed excellent breakfast and buffet dinners. Has a fun, funky vibe which is reflected through out the hotel. Has numerous sitting areas throughout. Rooms are generously sized with excellent bathroom amenities. Appears to be recently renovated. I’d stay there again in a heartbeat.
Great hotel! Highly recommended!
First time in Slovenia. Fun, clean, secure hotel. Breakfast was fantastic! 1970s theme with great decos! Modern flooring, shower/bathroom. Reasonably priced. Friendly helpful staff . Highly recommended. Free parking across the street.
Perfect
The best hotel I’ve stayed in Europe so far; It is new, comfortable, clean, breakfast is good, staff is friendly, relatively close to the center, we were very pleased with every aspect. I recommend it to everyone, you will be very satisfied, we want to go again.
