Maria's space is clean and comfortable. It is VERY hard to find, be warned, but let me tell you that it will be well worth the trouble. She and her friends make the process much easier, as she stayed on the phone with us while we stumbled through the famous Santa Cruz Barrio, to find two friendly women waiting out in the street to guide us in. The location is perfect. You will immediately be in the heart of the culture, with tapas and bars and restaurants around every corner. It's true what bloggers say, you will have a hopelessly romantic time getting lost in the streets of Santa Cruz. The Giraldo is within sight from the adorable balcony, and Las Setas and the river are a beautiful 5-10 minute walk, 20-30 if you let yourself stop at the bars or fun little shops you find along the way.
The decor is charming, it feels homely, but modern and comfortable. The bathroom was incredibly clean, which, admittedly, my wife can have pretty high standards on showers sometimes (I hope she doesn't read this review haha!) The point is if my wife was happy, and I would say she sets a pretty high bar for bathrooms.
I really don't know what else to say, this was well worth the money. If you're visiting Sevilla for the first or second time, the location is the perfect opportunity to feel like you're in the heart of the culture and love that Sevilla has to offer. Just the right amount of tourism, enough where you feel safe and confident, but not nearly where you feel like you're getting overcharged for an experience you could have anywhere in the world. And her space is just so well maintained that it's perfect to come home and collapse in with legs sore from wandering the meandering streets.
