Nuno's place is even better in person than in the photos. The apartment is modern and sleek, and the lighting is really great (for those who are into good apartment lighting). There is a beautiful balcony to hang out on, and A/C in each room to keep cool during the summer. The couch is also larger than it looks in the photos, and it's quite comfy. The location was perfect for my needs (well located in Copanema/Aproador area). I would stay here again in a heartbeat.
One thing to note for anyone with mobility issues is that there are small "steps" throughout the apartment; for example, a small step down from the common space to the bedrooms in the back, and small steps in and out of the bedroom and bathroom. This was not an issue for me, but I imagine it's a good to know for anyone with mobility issues.
