First of all, Hugo is an amazing host. Even though we have never actually met him, he did everything he could to make us welcome and comfortable.
What we loved about the apartment: very clean, very well equipped (except washing machine :), just like the pictures. Elevators. Great location. A very comfortable couch. Lots of natural light. AC (heats the place really well and fast). What we liked less: a bit noisy (faces a big street). The mattress felt too hard for us. The hot water tank is a bit small, and we ran out of water a couple of times - if you are two people (or more), take shorter showers, or use less water. The handles for the cabinets in the kitchen (including the fridge) are such that they can be hard to open sometimes.
Overall, a very nice experience - definitely would highly recommend Hugo's place.
