This is an excellent place with charming details of old apartment but with all the modern conveniences including a laundry machine and two air conditioners.
The weather was unbearably hot when I was there and having two separate air conditioners (one in bedroom and the other in main room) was a huge plus. They were very quiet. Kitchen appliances, including the washing machine, worked well. The bed was comfortable, and the bedroom had a plenty of space to hang clothes and store shoes and my belongings.
The location is fantastic. I never had to take busses. The old town is only 15-20 minutes away on foot. Even though the neighborhood was located in the center of seville, it was surprisingly quiet! People did get a little noisy (there are restaurants in the neighborhood as it is often the case in many european cities) during dinner hours, but all the noises died down after 11pm.
