Juan Luis's place was a great choice to stay in.
Everything was super easy when it came to checkin, since everything was ready we were even allowed to check in a little bit earlier..
The house is close to the historical centre (approximately 15 to 20 minutes walking), super close to a subway station (5min walk) and by subway, it takes 15minutes to the airport..
The house was very spacious, extremely clean, and there really wasn't anything missing, even in the kitchen, all of the basic instruments and gadgets were available.
Strongly recommend as a great quality/value place to stay in Valencia.
