We loved our stay at Carmen's apartment. It is very nicely decorated, functional and clean. It took us 15' to walk to the main areas of interest (Cathedral or Triana) which was very convenient for us, because we had a car and couldn't stay closer to the centre .
Check-in/check-out was easy and we absolutely appreciated the information our host sent us about Seville.
We did not use the bicycles. The same the kitchen facilities but the apartment seemed fully equipped.
a note to others: the parking space can be a bit tight, our rental offered us a small SUV which fitted fine in the parking area, but perhaps it would have been easier if we had a regular hatchback.
