This place appears to be a renovated apartment building. The apartments are large and come with an equipped kitchen (for an additional fee). They run about $50 - 120 a night, depending on size and include breakfast.
The place is kind of creepy, but seems clean and has secured parking, and a great location, but...it is above a very popular disco so I assume it will be very loud at night.
