We recently stayed for a few days in the wonderful city of Ljubljana and based ourselves in Kollmann apartments, apartment number 1. We couldn't have been happier with our choice of accommodation. The whole experience was a positive one. The reception staff are friendly and helpful and speak fluent English. There was a receptionist present when we arrived who handed over our room key and took us to the apartment, offering to carry our suitcases, which is on the very top floor of the building.
The apartment consists of a kitchen and living room area and a bathroom on one floor, then a bedroom on an upstairs mezzanine. The kitchen has two electric hobs and a microwave oven for cooking, although no oven. There is a refrigerator and an assortment of clean and well-kept crockery and cutlery. The whole apartment is scrupulously clean, modern and well-maintained, with no hint of the scrappiness and wear-and-tear that can sometimes be found in high-turnover rental properties. Every corner was clean and every amenity modern and functional.
The room has its own wireless router, meaning the wireless internet signal is strong. Although the internet speed is not particularly stunning (you won't be streaming HD movies easily) it's perfectly fine for everyday use such as reading the news, sending emails, watching the odd YouTube video etc.
The apartment is located in an absolutely perfect location, right in the heart of Ljubljana, meaning that you walk out of the door and straight into the fun and beauty that the city has to offer. There is a certain amount of city noise if you keep the windows open but, as central Ljubljana is pedestrianised, this means the sound of musicians playing and people chatting, not traffic noise. With the windows closed, this didn't keep us awake at all.
All in all, I would not hesitate to recommend this apartment. The only exception is that the apartment is not suited to the disabled or elderly who struggle with stairs, as access to the apartment requires climbing several flights of stairs. Since the building is a listed property, they are not allowed to add a lift. For those with no mobility issues, though, this is a great place to stay.
