Nacho's apartment was perfect for our 3-week visit to Seville. It's small but just the right size for 2 people. The apartment has all the amenities you need such as a washing machine, a kitchen with basic supplies and bathroom with bathtub and bidet. The bed was very comfortable.
There is also roof access on the top floor where you can have a nice view of the city and hang your wet laundry.
As previous reviewers have noted, the apartment has no exterior-facing windows. All windows face the interior courtyard and it can be a bit dark.
The apartment is very affordable and the location is great. Lots of shops and markets are nearby and it's a short walk from the heart of Old Town with the Cathedral and Real Alcazar.
Nacho is a great host and quickly replied to any questions we had. We would definitely stay here again if we come back to Seville.
