Hey,
Apartment itself is described very accurately. Might be a bit tricky to find at first cause Alameda street is pretty busy :) But don't worry - just give Miguel a call, and he will point you into a right direction.
In general, location of the apartment is really great. It's located besides Alameda de Hercules public park. A lot of restaurants, bars, nightlife activities nearby. Also, as far as I know, the neighbourhood is pretty safe.

Really had no issues with our stay in Miguels apartment, definitely would book this place next time we visit Seville!
In addition, Miguel was an excellent and helpful host!
