Karoline is in a quiet, residential area with several cafes and several supermarkets just a few minutes away. A bus-stop is just outside the building, a metro station is 5-10 minutes away and the West Railway station is 15-20 minutes away. We had only 4 people in our group so the apartment was very spacious and comfortable. A housekeeper lives in the same building and she was available to welcome us, answer questions during our stay and was very helpful. The owner was available by phone through the housekeeper and by email and was also very accommodating before and during our stay.
Bed was a bit hard but did not stop us having a good night sleep. Easy access to old town by bus 57a, short enough to not be a problem (10 minutes aprox). Too far to walk, but bus seemed to always be there when we needed it day and night. Don't expect 5 stars, but that is not what you are paying for. Bus very simple to use, same bus 57a does loop into city (terminates close to opera) and then returns from same stop ( can not get easier than that).. You will get clean sheets and towels, a large living area, smallish kitchen, plenty of furniture and convient close secure parking. Wifi was good, managed to service our electronic device rich family's!!
Only negative side was that English speaking owner is not your point of contact. Romanian women who lives in building who speaks no English is. Made it a bit difficult to get that important 'lay of the land information' ( eg where to catch bus and buy food). Having said that we did manage, and she tried very hard to help us settle in. All in all, I would happy recommend it for a family.
