Great stay at a great location. The accommodations were as described and all setup for the four of us when we arrived. We only used the elevator for luggage. The stairs were very wide and not very steep so an easy walk.
The location was very convenient. 35 minute walk was our longest and that was to the Vatican museum or the Spanish steps area. Everything else we wanted to see was 20 minutes or less. There were trolly and bus services on adjacent blocks.
The food was great. The location was close to the river and we found a wide variety of food options in all directions. Several grocery stores nearby that we used several times.
With the restaurants across the street and nearby you are not walking through empty streets on the way in and out. We like that it was not a main elbow to elbow tourist street. There are several secure doors to get to the flat.
Spring temperatures so we did not use the heating or cooling system. Opening the windows rapidly filled the rooms with fresh air.
