We had an absolutely fantastic stay at Marta's apartment. It was perfect, clean, everything that we needed was there, couldn't fault anything about it.
Marta was extremely helpful, we were staying whilst it was very hot and we asked if she might have a fan we could use, Marta's mum dropped us round a fan the same day. Location is also great, very near lovely restaurants and 5 minutes walk from a great metro line that takes you to all of Rome's main sights.
I can't recommend staying here enough. We will definitely be returning!
