Really enjoyed my stay at Mercedes and Omar's apartment! The place itself is situated right in the midst of the city so there's tonnes of spots you can visit within walking distance, any direction you choose.
Mercedes was a very sweet lady who welcomed me immediately and had plenty of helpful tips for traversing the local area.
The apartment itself was very clean and tidy with mostly anything you could need provided for you (towels, blankets, heaters, hot drinks, etc), whilst you always had access to the hosts staying in the upstairs block you are given complete privacy in your own room.
Didn't manage to take advantage of the breakfast service provided myself but based on my interaction with Mercedes I'm sure it's a great way to set you up for whatever you have planned in the great city of Seville.
Only downsides are the Wi-Fi quality in my room (which Mercedes did disclose with me beforehand and I coped with my mobile data anyway) as well as the secondary downstairs bathroom not being designed for people above 6 feet tall haha (Again the main bathroom is sizeable enough for anyone so just plan your bathroom visits around fellow guests and you'll be fine).
I reccommend staying here if you're looking for an affordable, clean and well located lodging for a weekend or longer; enjoy the sights of Seville if you do so :-)
