Pilar's place was in a great location - walking distance to many attractions. A great starting point to explore the city and great value. The hosts were very accommodating and the place was well equipped.
Unforunately we had a mosquito in the studio which bit us during our stay - I believe it came through the bathroom window which doesn't have a fly screen (or a fan to remove humidity). My eye was bruised for a day due to a bite on the last day - tried killing the mosquitobut it evaded us due to the high ceiling of the studio. This was quite situational so I'm sure not everybody will go through this, but would prefer fly screens in the bathroom to avoid this happening.
Also, you need to climb two sets of stairs so probably not the beat place if you aren't very mobile.
Overall a good experience. The mosquito wasn't the fault of the hosts but thought I'd mention it as Seville can be quite a humid city, particularly due to little ventilation.
