First, the positives - the apartment is well located, has all the amenities (except one, which I'll get to soon) you may need, is nicely furnished.
Inspite of all the positives, our experience with this apartment was terrible. At arrival, we were greeted by a stained toilet with a malfunctioning flush. The host gave us a way to work the flush, which was not really useful. After contacting him many times about the flush, he insinuated that we had dirtied the toilet ourselves. A clean, functioning toilet is a basic facility that we've never had to ask for in all our travels.
We ended up staying the night because we had an early morning ferry and moving to a new place with our bags and baby would have been a hassle.
My suggestion to anyone looking to stay here is to look for another place and to the host is to be more respectful towards your guests, we are not all lying, crazy people.
Honestly, this experience ruined wellington for us.
