The space was perfect for us. It was nice and spacious and very well located in the historical center. Although central, it was not noisy at all inside the apartment.
We travelled with our 6 month old baby and there was a play pen available for him in the apartment. We did use a carrier to bring him up and down the stairs just to be safe but otherwise it was fine. We were able to leave the stroller at the bottom of the steps and felt comfortable doing so.
