We had an amazing time staying at Flora's place. The location is very central, just a few minutes walking to most key places in Chora. And the apartment is so beautiful -- we felt completely at home. The place was spotless and extremely modern. And Flora is the best host you could ask for. We arrived several hours before check-in but Flora was kind enough to let us leave our luggage in her mother's apartment just above. We were also able to check in a bit earlier than expected.
We arrived by boat -- it's about a 10-15 minute walk from the port with some elevation, just something to keep in mind. It is possible to avoid stairs if you take a specific walking path.
Would highly recommend and would definitely stay again if we visit Naxos in the future!
