I would generally recommend the apartment because of 1) nice location close to restaurants, metro, walking distance to Old Town (15 minutes), 2) cozy, beautiful and clean place, 3) very nice and accurate host.
However, things to note are: 1) VERY noisy as located on 1st floor on a main street next to 24/7 pizza place, not good isolated due to old (but beuatiful) windows, 2) hard and uncomfortable bed - we spent there 5 nights and after the 2nd both my boyfriend and I had pain in lower back (we are 30 and typically no pains).
