Concha was amazing and kind! She went above and beyond to make our stay easy and enjoyable. We arrived early and Concha allowed us to store our luggage at the apartment. Though we had awakened her, Concha took the time to make coffee and talk with us for an hour about what we could see and do. She also provided us with maps.
Concha did not have an iron, but went out and purchased one so that I could iron my clothes for a presentation I was doing. Concha went above and beyond again when she woke up at 0445 hrs to be certain our cab arrived (which she ordered the evening before). When it didn't, Concha went out in the rain and hailed us a cab.
The location is perfect, right in the middle of the Gothic District. The apartment is located in the city, so you will have typical city noise, which should be expected. Also, Concha snores and her room is directly below. If you are bothered by city noise or snoring, you may consider ear plugs.
Concha's flat is a great value and she is a wonderful host.
