Something different. A small modern hotel in Vallecito about 10 minutes walk from the centre (it really is close and walkable in the day). Small quiet street and off street parking for 2 cars (no problem using the street. You may hear a bit of traffic from a main road nearby at peak times but you are in the middle of the city and it really isn't a problem and isn't at night.
Tries hard to be a funky boutique which may not be everyone's taste. Rooms are reasonable size with good beds and well finished bathrooms. Hot water works w/o problem. Good wifi. There is a roof gym and I think a roof terrace but we didn't use. Cosy dining room with an excellent breakfast. Also do lunch and dinner but we didn't try.
In short a find. Half the price of the cosy and nicest old centre hotels and much better than several of the centre offerings. Perfect base for exploring the city or a business trip. $59 for a double
