Easily one of the cleanest, most amenable apartments I've stayed at.
Very tasteful decor, amazing air conditioning and stunning location.
The apartment is located in a typical Spanish building with a center courtyard decorated in Andalusian style, very quiet and peaceful, but still steps away from the nightlife and tablaos in Triana. It's also very walkable if you mean to hang out downtown, a pleasant 10 minutes walk.
Ideal if you are travelling by car or are on a budget, as there are many markets and a public parking close by.
Maria Teresa is a very friendly and lovely host, although I would suggest having a phrasebook or Google translate with yoh if you are not comfortable making yourself understood in Spanish.
All in all a great experience!
