I had a very positive experience with Next Step. I worked with Katie after a recommendation from a friend, and she was great!
At first I was concerned about the fact that there are no apartment listings on the website, but very quickly was reassured that this means Katie could search for and show me only the listings that were most relevant to my search, rather than misleading or unavailable postings that you might see on other websites.
Katie definitely responded to the feedback I gave as we went to viewings, so that each time we met, we only saw apartments that fit my requirements and were improvements on the last. I would definitely recommend to anyone else trying to move in the most stress-free way possible!
