Silvia is great at communicating and responding to messages. She was so nice to accommodate us when we needed a late checkin and was very flexible when we ended up arriving earlier than expected! We were welcomed into Silvia's apartment by her uncle who also lives in the building. He was so lovely and took the time to show us everything we needed to know. It is a tiny apartment but has everything you need, including cooking equipment and a mini fridge, also air con that works perfectly!! The location is great - you can use an option of metro stations that are close by (between 2-5 mins walk), plus you can walk to the colosseum in about 10-15 minutes depending on the route you choose. Neighborhood around the park can be a bit dodgy at night but we are two young women and found it to be fine as we just steered clear of it at night. We loved the restaurant across the street from the apartment, so much so that we ate there twice! I highly recommend the pizzas!
