We stayed at the Katrca 1905 Hotel in Ljubljana for 4 nights and it was a very pleasant experience. The hotel rooms are modern and clean with tea/coffee making facilities, fridge with welcome drinks in it, AC and LCD tv as well. The breakfast was quite good and it offered different cereals, deli, fresh fruit etc.
The hotel is in a quiet residential area about 15 mins walking distance from the centre of Ljubljana. It is very good value for money and some of the service we were giving went beyond our expectations. Just one last advise try out the hotel's restaurant it offers good food at very good prices!!

Do not book this place! I made a booking there and even though they said someone would be there till midnight to book you in, they had locked all the doors and left me stranded with mo where to stay

I stayed in Katrca for 4 nights with my friends in October 2010. The room was little bit small, but clean and nice furnished. I have to recommed restaurant in Katrca, meal was tasty and not so expensive. To the centre is it about 20 - 25 minutes by walk. Location was very good for us. It is situated near dormitory for students, where is accommodate my sister (Socrates Erasmus student). If you have car, you can park next to the building on the parking lot.

Trattoria Kartca is in a convinent location, not far from the city center (20mins on foot but you have to pass by some not really nice areas). Formerly it was called Gostilna pri Katrci, but it has been refurbished and rooms are fairly spacious (some more than others) and bright.
The rooms are on the first floor, while on the ground floor there is a restaurant. The breakfast is usually served in the restaurant.

My boyfriend and I arrived on the 30th december and were very satisfied of the room: clean, tidy, lcd TV. We also had a good dinner at the restaurant. During the dinner we were informed that the restaurant was going to be CLOSED on 31st and 1st..we would have prefered to be informed when we booked since we chose a b&b accomodation in this not- centrally-located place, also because of the restaurant: after an entire day visiting Ljubljana we wanted to avoid stressful restaurant research!
Actually finding an open place was the main problem in Ljubljana during those days...EVERYTHING was CLOSED! On the 31st it was surreal: thousands of tourists walking around the city center looking for a place to eat! The only 3 open places (one restaurant serving a very expensive menu,a nother one "a la carte" and a pizzeria)were totally full! At the end we had dinner at a kavapcici kiosk while it was raining!
When we came back to the accomodation we also found some paninis in the fridge that weren't there the previous day..the following morning we realised them to be our breakfast!! Breakfast room was empty and we just had those COLD paninis, no coffee, juice, yogurt, cereals....
In addition, given the absence of staff, our room wasn't cleaned during our 3 days stay.

On the 1st we went to LAKE BLED, really really nice place and, moreover, a number of restaurants, cafes and even some shop were OPEN!!

In conclusion, Ljubljana is a nice city, it is small and one day is enough for seeing it all, but avoid it during new year's days..
Katrca is a fair accomodation for those who like to be out if the crouded city center and are travelling by car (a number of parking spaces in the nearby).
