We really enjoyed our 3.5 week stay at Carmen's unit. It is bright and cheerful and very comfortable. The layout of the unit is great, it feels spacious and efficiently organized. There were three sets of floor to ceiling window/doors that let in amazing light in the bedrooms and main living space throughout the day. The beds were very comfortable and there was plenty of storage for our clothes and suitcases. The location of Alameda de Hercules was perfect for us. It feels like more of a "locals" neighborhood as it's not immediately within the most touristy part of the center, but it's only a 10 minute or less walk from all of it. There are so many restaurants and bars and shops and markets around the unit which we loved. The tradeoff for this bustling neighborhood is that there is street noise at night as other reviews have mentioned. But for us, with some earplugs for sleeping, it didn't effect us at all and we would choose this neighborhood again, especially for a longer stay like ours was. The unit is not shiny and brand new and could use a little TLC, but putting that aside, we had a really great stay in Seville and found Carmen to be a gracious host.
