The Niche Hotel was gorgeous. Such a beautiful boutique hotel in Athens. The service from each staff member we encountered was excellent. We stayed in the best room, overlooking the Acropolis and the view is phenomenal. Comfortable bed, luxury feel to every detail.
The only negative feedback would be that the hotel is located on a main road so can get quite noisy and, as it's located right under the rooftop bar/restaurant, you can hear the chairs scraping against the floor above you.
