Great location in a small studio at Via della Scala!
I had a nice stay at Issac's property located along Via della Scala. I would say the biggest stand out would be the location of the property is amazing. The Trastevere are has great variety of restaurants, gelato shops and night life, walkable distance to most attractions too. Issac's colleague, Loredana, was responsive and helpful over WhatsApp during my 5D4N stay.
The apartment itself is smaller than what the photos let on, but adequate enough for two travellers. It's well furnished too, which was great. The only downside of the apartment would be that the bed is a pull-out sofa bed with a very thin mattress and hard foam pillows. I couldn't get the most comfortable sleep and woke up pretty sore on most nights. I wish I had taken better notice of this this in the description and pictures and before I booked the place because comfort is a pretty big consideration for me, so do take note fellow travellers.
