"What a charming hotel. The amenities were top notch and the view absolutely stunning. The staff was also incredibly kind and helpful. The air conditioner wasn’t great, and that’s something I find to be a necessity when traveling, but thankfully I’d brought a mini fan, so it worked out well enough. ..."
