We had an amazing stay at Cecilia's apartment. It is has everything you need for 2 people. While there isn't a living room area, the bedroom has a small seating area which is nice and the large roof terrace is amazing to unwind after a day in the city. The air conditioning worked great, we needed it in the hot summer. The kitchen is small but has anything you need. You have the means to make meals, but beware the stove has only enough space for two small pans. We were provided with basic kitchen supplies like salt, sugar and oil. The apartment was very clean and felt very modern.
Cecilia herself wasn't available when we arrived. We were welcomed with the Italian lady Theresa. She didn't speak one word of english, but luckily we still understood each other and shortly after another (English speaking) lady arrived. There's a small map available with local tips and restaurants in Trastevere.
The apartment is located in a nice area, with lots of local homes around. You don't feel like you're in the big city here. The supermarket is about 3 minutes away. All and all an easy route to the city. There's a 10 minute walk to the Trastevere train station and from there you can get a tram (8) to the city centre which takes about 15 minutes. This tram goes almost every 5 minutes and in our experience it wasn't that crowded. As said before, the 10 minutes walk to the apartment is uphill tho. Once you get to the apartment, you still have a few stairs to climb. We visited in the summer, so the glass staircase was always extremely hot when we arrived. I personally was a bit tired of the walk to the apartment after about 8 days of taking that journey 4 times a day. Thus, I would highly recommend the place when you are looking for a (long) weekend getaway! But when you are staying longer, please be aware of the journey to and from the apartment.
