Corso37 is in an excellent location. We walked everywhere, even to the Vatican. All the shopping you could want is in this location. A supermarket is only a few minutes walk away. We were warmly greeted and helped with bringing our luggage up the three levels of steep stairs. The apartment was clean and smelled nice. The washing machine (and laundry liquid) was a treat - we had been traveling for 2 1/2 weeks at this stage. We especially appreciated the umbrellas provided on our last night. We were about to go out for dinner when it started raining, heavily. Overall, a great stay in Rome. Highly recommended.
