Wow! What a beautiful house in the middle of the historic centre... Staying there is definitively a very special experience. If we come back to Sevilla, it's the place we would go to again :D! Very interesting house, perfect location, very nice house keeper, fair price...
Some things to consider if you book this room:
-) climbing up the upper bed is a bit of an adventure at first (it is save, but if you think this might be an issue, it's better to book one of the other rooms)...
-) The balcony faces the narrow street, so if you open the windows it can happen that tourists stand there, watch, take pictures etc.
-) the bathroom is shared, sometimes this requires a little bit of flexibility
But again: we definitely recommend the stay in the house and the room!
