I'll try to summarize my experience in 4 points:
1. Location. Excellent, next to Cathedral, la Giralda, the Royal palace.
2. Clean and warm. Manuela took great pains to ensure that our room and breakfast area was warm.
3. Quiet. Located on a side street and facing an inner courtyard, we slept very well.
4. Warm welcome. Manuela helped me with my bag up the stairs and gave us pointers on where to go, etc. A lovely person.
