We had a really nice weekend in Seville, also thanks to this nice apartment and its host.
Location is superb, just around the corner of the cathedrale and with many shops and eateries around.
Be aware that you need to park your car in a public garage and walk with your stuff to the apartment (like 10min).
The apartment is really nicely designed, with many creative ideas that make it very special. Downside is, that keeping all those beautiful things clean needs some effort. It wasn´t "big dirt", but it was also not spotlessly clean. The furniture on the small balcony serves only for decoration; the stools are neither comfortable nor safe to sit on.
The apartment is big enough to fit three couples, and has a very good layout. We stayed only as two couples, which made it a bit too pricey for those two nights (but again: we were aware of the cost when booking, so there were no surprises to us; just a "we should have thought about that").
If you are sensitive to noise, please note that it´s a old building and somehow we were able to hear the neighbours talking loudly.
