We stood 3 weeks in Cristina's apartment. The apartment is in a great location walking distance to two botanical gardens and all the Belem sites. It is also just a quick ride into downtown via metro or a 5-10 minute uber/taxi.
Cristina was a great host answering all of our questions. A great apartment with accurate pictures. The kitchen is well appointed and the bed is very comfortable! All in all it was a great stay!
