We enjoyed two nights at the Zero Hotel during a short visit to Valparaiso. The hotel is in an "artsy" part of town peppered with hidden stairways, lots of murals, great restaurants, artisan shops, and friendly people. The people who manned the desk were always lovely and helpful. The breakfasts were delicious and filling. I would say that the one negative is that the rooms do NOT have air conditioning. If you sleep with the windows open, you are kept awake by the outside noises including screeching birds, traffic, and people yelling/talking.
