My favorite part about this flat is most certainly the location. Trastevere is the place to stay in Rome, at least for me. After a long a day in the city, it was very enjoyable to come back to this adorable area, rest and later go for dinner and drinks that were just a minute away. Food in Trastevere is not only better, it's cheaper. That makes it all worth it even more! However, despite the fact that this flat is in the heart of Trastevere and just steps away from bars and restaurants, it's also on a quieter street and is quite high up so you hear no noise at all. That was marvelous as the area gets very busy.
Ekaterina was very responsive prior to our visit (I asked her a few questions), very kind and understanding. She let us leave our bags at the flat as it got cleaned and then to leave them there when we departed. Valentina, who checked us in was just amazing - such a pleasant person all around and extremely helpful.
The flat is exactly as on the photos. It's clean, rustic and has everything you need. It has airconditioning in both bedrooms which was very important for us. The minuses? Not many - one it's on the 3rd floor and there is no elevator, which is quite common in Europe so I wasn't bothered but if you have a baby with a pram it might not be great. The second part is the fact that the bathroom is in between the bedrooms, it's a bit strange unless you're a family a very comfortable with each other. We came us 2 couples so that was kind of awkward but we managed (no big deal at all).
Overall, even the small faults of the flat did not matter as we had a very comfortable stay - we felt safe and enjoyed the area so much.
