It's the Marriott, you really can't go wrong. But let's break it down a little. The staff. I know it's Japan and hospitality is their thing, and I know it's the Marriott and the overall experience is #1, but holy cow. I'm not sure just how authentic those smiles were, and I don't care, it made my day every day, multiple times a day. We were greeted by an English speaking concierge who helped us get checked in, and the rest of the time we got to practice our Japanese to the happiest staff I've ever seen.
The room was incredible. The bathroom opens up or closes completely with sliding doors, allowing privacy or opening the room wide. The toilet room was separate with another sliding door (which I'm loving in Japan) to save space. The bed was a king and super comfortable. Our room overlooked the city center, another perk.
The breakfast buffet was unbelievable in the best way. We made use of it every morning. A blended selection of Western and Japanese dishes, and everything was seriously amazing. We didn't get to try any other restaurant in the hotel, but did partake of some of the grab-N-go treats, because we love desserts.
The hotel is right next to Nagasaki Station, and a large mall, not to mention a street car station so it's extremely convenient to get around. It's the Marriott, you can't go wrong here, but still we loved our stay and will come back again.
