A lot of good things about the appartment have been mentioned in previous comments. I only can confirm that all those good things happened to be true). The location is really great. Everything in old city center is stone's throw away from the appartment.
But actually the location in the old center nearby the restaurants was my real concern before the trip. I was anxious that it might be noisy at nights. To my greate surprise all music in restaurants was turned off about 21.00, and it was super quiet and pleasant at the night during my visit.
Ilvars is very helpfull and responsive. Due to his detailed discription and photos there were no problem with finding the place and check-in process. I really liked that there are a shower and a bath in the bathroom. Everything was great and I definitelly recommend to stay in Ilvars appartment.
