This apartment was perfect for what we needed! It was really clean, the beds were comfortable and you had everything you needed in the kitchen. The apartment is in a great location, just a couple of blocks from the top of Piazza Spagna (Spanish Steps). From there, you can get a taxi (taxi stands are only in certain locations), or jump on the metro to any other destinations. You're also within walking distance of many other popular sites in Rome. I will note that the apartment is at the top of small hill, so you walk "down" to many sites but you will need to walk "up" to get to the apartment. It's not too strenuous - my 73 year old dad was with us and he was able to walk it - just a little slower :)
There are a couple of markets nearby and a café just at the bottom of the street where we picked up coffee and pastries in the morning. Lots of conveniences close by.
Mirca was great with communication and allowed us to drop off our bags prior to check-in time - this was really helpful! She has plenty of Rome maps and books in the apartment, so you have lots of information at your fingertips.
Overall, our stay was wonderful and I would highly recommend Mirca's place!
