Normally my wife and I are the type of travelers who stay in the cheapest possible accommodations, e.g., youth hostels. For our trip to Sevilla we were staying in one place a bit longer than usual (10 days) and I needed a fast internet connection to stay connected to work. This apartment was well worth the extra money (still cheap by Paris standards, where we live). When we arrived Maria was cleaning up after installing some new lighting. The apartment now has plenty of lighting options, including a skylight. It will never be a sunny apartment, being on the ground floor of a building on a one of the narrow streets of the old town. It's by no means a dank basement though. The windows allow good cross ventilation and the lack of direct sunlight probably keeps it cool in summer (we were there in February).

The apartment is in the absolute best part of town near plaza Encarnación. It's right around the corner from some super authentic neighborhood tapas joints (Santa Marta and Los Dardos were two of our favorites.) However, the apartment is on a small street and stays absolutely quiet even on weekend nights when the neighborhood is buzzing. There is a bit on noise, such as doors opening and closing, around 9-10AM when the neighbors leave for work, which could wake the lightest sleepers.

The apartment itself is really an marvel of design. I doubt that such a place would even be available were it not for the economic slow down in Spain, as the owners were using it as a work space. Although her training is as an architect, Maria is a very gracious host. Her recommendations were definitely right on, especially for those into the more prefer the bohemian to the touristy. When you finally get sick of traditional tapas, the restaurant Panandor (also just around the corner) is an absolute revelation. Contenador is another great one (Eslava was meh). The apartment has everything you need and comes fully stocked. The internet was fast enough to watch movies on the very high quality big screen projector using my laptop (after a bit of fussing with cables), which was really great.
The bed was pretty firm, but we found it to be really comfortable.
The shower had one of those waterfall shower heads which was also really nice.

Sevilla is a great town. On a nice day I recommend grabbing some of the public city bikes and heading to the Parque del Alamillo or just taking the road around the periphery of the old town which has bike paths.

We had a great time in this apartment, I give it the highest possible recommendation.
