Diana is a very nice person who is running a sort of B&B located directly in city centre. She was very helpful and showed us some main attractions on the city map when we arrived, and she provided us with some insider tips. As described in the offer, it's a simple room with a shared kitchen and bathroom area.
However, at least our room downstairs was badly soundproofed so we could hear all conversations and footsteps in the apartment above. Also, the apartment would benefit from some repairs and regular maintenance work. For instance, the shower head fell down, but we told her and she replaced it right away so we assume everything is fine now. :)
