The best thing about this apartment is the location! It is very close to the Trevi Fountain, shops, and restaurants. We felt like we were in the heart of Rome and walked to many places from the apartment. There is a lovely courtyard, and the area seemed very safe. The apartment itself was fine, with basic amenities and wifi available in the main living space.
The only negative is that there is not a self check-in option. Our flight was extremely delayed, and the wait for a taxi from the train station was very long, so we decided to walk to the apartment from the Termini, making us late to meet the steward who was checking us in. We had one phone with international service and texted the steward to tell him that we were running late. He was frustrated when he met us at the apartment, because he had to wait so long. We understand that he waited for a long time, but we let him know that we were late and continued to text him updates as we got closer.
This apartment was a nice place to stay, and we enjoyed its proximity to everything in Rome, but if you are unsure of your exact arrival time, or there is a possibility that you may be delayed, you might want to consider an apartment with a self check-in option.
