Blue river was really nice. I came here with my friend and we found the place very clean, fully furnished with everything needed for cooking and with maps of Rome. It has a lovely Japanese- styled decor and feels very bright and airy, despite it being a very small flat. My friend and I chose to walk everywhere and managed to see every thing we wanted in 4 days so we would say the location I great- although if you do plan on walking bring comfy shoes! It's really near to the train station, and also close to trastevere where you can find great apperitivo :) Also, the neighbourhood is really safe and the people are lovely and happy to help in the nearby shops. There's a great indoor food market just across the bridge 10minutes away by foot and on one of the days- might have been Monday, there was a huge out door flea market that started just 3 minutes away from the flat. Which was an amazing experience.
Thank you Vicenzo for your lovely flat, I definitely recommend it for pairs, couples and perhaps groups if three if you're ok with sharing a double bed.
