The room was small, but very nice and cozy. The private bathroom is definitely a plus, as were the kitchen and living room. The room is absolutely quiet and quite comfortable for one person. It's easy to keep one's privacy, but I could also get in touch with other guests, if I wanted.
Although I didn't see Sylwia once during the three weeks I spend there, she was very helpful whenever I had questions. The only problem was that she had forgotten to tell me where she had left the keys when I moved in, so I had to wait for half an hour, until she answered her phone. She was very sorry and apologized, so it was never a real issue!
