The location of apartment was fabulous, we were a couple minutes from Colosseum and able to visit all the major sites easily from this home base. Great restaurants were available within easy walking distance in any direction. Don't miss "Ciuri Ciuri" pastry shop nearby, it's beyond amazing.
The apartment is very small, but this is to be expected for an apartment in Rome and is as advertised. It was cozy but comfortable. Plenty of outlets, a full kitchen and a converter was even provided for convenience of US guests.
On the down side, there was no heat due to building-wide boiler shut down for Spring (we could have used it a couple nights) and on the last day there was no hot water for showers, which was VERY uncomfortable. Wifi is only accessible in hallway, works best if you sit on floor by front door - not ideal! Lastly, there is a flamenco dancing studio underneath which meant a lot of music and stomping in the evenings, otherwise very quiet.
