THE APARTMENT
Pros:
We were very comfortable here. The apartment is spacious and well appointed, with comfortable beds, plenty of seating areas, a large bathroom, a lovely outside terrace and fairly reliable WiFi. There are lots of windows to bring in the light and the outdoor sounds, but they close tightly when you don't want either of those. There is a desk area which worked well for our laptop and lots of electrical outlets to keep our devices charged.
Cons:
The things I would mention are that the kitchen is very small..only one person can be in there comfortably. Also, the apartment is 2 floors up...if you have mobility issues, this could be a problem. We found it challenging getting suitcases up and down the staircase and if you are uncomfortable climbing stairs, especially at the end of a very busy day, keep this in mind.
THE LOCATION
The location is perfect with easy access to Barrio de Santa Cruz ,three minutes from the cathedral, the Giralda and the Alcazar . Restaurants are close by and we found it to be very conveniently located.
OTHER
If you are from North America, be very aware that appliances in Europe are different than what you are used to...we have used Airbnb all over the world and in every other place we have stayed, there has been a binder of some sort with house rules, instructions for using appliances, information on trash pickup, restaurant suggestions, etc. There is nothing like that here ( we didn't even know where to put the trash ) and the specific use of the washer caused us no end of problems. We had such difficulty getting Maria to respond to our requests for assistance with it and quite frankly, it occupied far too much of our holiday time. We rent spaces with washers, and pay the extra cost for same so we have the convenience of in house laundry facilities and when getting the laundry done becomes the focal point of our vacation, something has gone very awry. Just heads up...make sure you know how to use European appliances before you are left to fend for yourself.
