Check-in at Alberto's place was smooth. His instructions - easy to read - his communication great, so all done swiftly!
Location-wise, the apartment is seconds away from a buzzing square where there are plenty of restaurants / bars (full of locals) and even a farmers market on a Saturday - I highly recommend!
The apartment is a 20 min walk from the centre of Sevilla; the apartment itself was very clean and easy to find.
For drivers, note that the parking space is between two pillars so big cars won't fit in the space. From our experience, private garages in Spain are quite tight, so one to be weary of!
All in all we had a pleasant stay and I would recommend. :)
