We had a good stay at Raimundo's apartment. The place itself is spacious and very modern which gives it a clean feel. The location is very convenient (near beautiful Praca das Flores) and we had an easy time communicating with the host, who kindly accommodated an early check-in. If you're looking for a "cozy" or "charming" experience, this is not the spot, but if you just want a practical and comfortable place to crash for the night, this is perfect.
That said, a couple of cleanliness and comfort-related items keep us from giving this a 5 star review. The apartment itself (floors, bathrooms, sheets) was very clean but the futon and tablecloth could use a good wash. There were no trash cans in the bathrooms (!), kitchen supplies were not in the best condition, and there was no laundry detergent so we had to get our own. The futon downstairs is not a comfortable place to sit because of its shape and fact that it has no cushions.
Overall, a good stay. But keep the above in mind before booking!
