We find the apartment very stylish and functional. You find everything where it should be and the most common amenities you need: Coffee maker, tea kettle, dishwasher and washing machine. Our kids particularly love the high bed and the stairs leading up to it. The apartment is also very clean. The location is very central, and we were able to walk to most tourist sites. Gustavo was also very responsive and friendly.
The only thing that could make our stay more perfect is that, if the bedroom could be enclosed so that when the kids are in bed, we could still do things in the living room. In our case, we were forced to stay quiet in the living room until the kids were asleep. Again, this probably only impact us with young kids. If all occupants go to bed at the same time, it wouldn't be an issue.
All in all, we really enjoyed the place and would highly recommend it to fellow travelers. Thanks Gustavo.
