Paola is an amazing host, very warm and friendly! I had issues on my arrival day and ended up checking in later than expected, and she was very understanding and kind in that situation :) In general, the communication was great.
The location is great - it's in the lovely old town, and one of the first things you see when you go outside is Porta de Serrans/Torres de Serranos. The North Station, from which you can travel all over Valencia (and beyond), is about 15 min away on foot. The flat is also well-equipped. There's no kettle or electric coffee maker, but there's an induction stove and a microwave, as well as a number of pots and pans and even a couple of moka pots! So making tea and coffee is definitely possible. There's also a washing machine and laundry detergent so that's great.
