We had a wonderful time in Sevilla and really liked staying in Cristinas apartment, which seems to be fairly new and was very clean.
The flat has everything you would need for a short trip however, keep in mind it is really really small. The apartment is situated in calm neighbourhood of central Sevilla. You can reach all the beautiful sights, supermarkets and restaurants by foot.

In the morning it can get a little louder due to singing school children walking by and since the aparment is right on a street commonly used by motobikes and cars. However this is not a dealbreaker.

Overall we can highly recommend Christinas apartment to anyone that wants to spend a few nights in Sevilla!
