Everything was perfect!
Yolanda was extremely flexible with us on check in and check out.
The apartment is as described. Everything that you may need is provided (internet, kitchen is well supplied, dishwasher, washer...). Yolanda provided us as well a baby cot with all the bed sheets.
It is very clean in a great location (center of Sevilla) in a nice building. The patios are very pleasant and brings freshness (AC is also available in the apartment).
The apartment is pretty big (nice bedroom, bathroom and living room).
We will definitively come back there next we are in Sevilla!
