The apartment is well located in the old town a short walk from every major sites of Sevilla. It is perfectly comfortable, well decorated and well maintained - you can see it is used for short stays as everything is in - just what you need - nothing else.
It works perfectly for us with a baby as the flat is well equipped and spotless. The host was absolutely accommodating as they sourced a very nice baby cot (in wood), with baby linen, pillow and duvet for our daughter.
Downside is probably that the streets can be noisy at night with pedestrians passing by as it is in every old towns with ancient buildings but it is manageable. Photos also make the flat look bigger than it really is but it is perfectly well described.
It is definitely a place to recommend for a small family, and Patricia/contacts are totally trustworthy.
