The apartment is a good size and could comfortably sleep 6. The stairs to the master bedroom and terrace are a very narrow set of spiral stairs as pictured, which was only tricky for us when taking the baby upstairs. The stairs to get to the apartment are also quite steep and narrow, so pack lightly and don't buy too many groceries! :) They have done a good job of using the space well and maintaining the charm of an old building. The views and sounds from the neighborhood are lovely, and we were able to easily walk to all the major attractions.
