3 of my friends and I stayed at Pacos Place for a few days as part of our summer girls trip. Its a lovely flat located above two very nice bars where we enjoyed one or two Tinto de Verano in the evening. :-)
It was a really accommodating flat with all necessary utilities, although it is to say that there is only one bedroom, so be aware if you have light sleep.
The hosts were really helpful and professional with all questions and matters we had during our time in Seville. Would definitely recommend!
