I spent excellent 5 days in Valencia and being able to stay at Susi's place had a great role in this. If you are looking for a very warm and caring host, Susi is the person. My flight arrived earlier in Valencia than the official check-in time but this was not a problem. Communicating with Susi was super easy and operative. I got a lot of good tips from her as well (including on where to get Valencian paella just for one, on museums and places to visit etc.). The apartment is in an ideal location - very close to the Colon metro station (direct metro from the airport in 20 minutes+ ca 6 minutes to Susi's place) + the Colon market, next to the impressive Turia gardens, only some 15 minutes by walking to the old town and ca 3 km to the beach. The room itself is spacious and has everything one needs for a shorter or even a longer stay. As others have written, and Susi does not hide herself, you can hear people and cars outside in the night as there are bars on the streets etc., especially during the second half of the week/ weekends but Susi had even provided earplugs for this. On the other hand, the first half of the week was very quiet.
Susi also provided breakfast, which again, I had not expected.
To sum up, I would definitely recommend staying in this place. And I would do it again if another trip to Valencia were to happen.
