Overall, a wonderful experience. The hotel is very new and considering there is no actual desk staff on-site, communication about how to find the hotel, check in/out, and store luggage was pretty good. However, they do text you or use WhatsApp so you'll need to make sure you have wireless service abroad, or you'll be out of luck.
I only have two complaints. First, we reserved a room with a terrace. However, when we checked in, our room had no terrace but instead had a kitchenette, and upon checking our last contact from Numa I found we had been "upgraded" to a studio room. I'd rather have had the terrace and would have appreciated being informed that I wasn't getting one if it wasn't available. Second, there was a long hair on one of our clean towels at check-in. Otherwise, the room was very comfortable and the location is convenient to restaurants, transportation, etc. Free on-site storage for luggage was a huge plus, as we arrived early and didn't want to drag our bags around until check-in. We didn't use the on-site laundry facilities but were glad they were there if we'd needed them.
