I stayed in this apartment for 2 nights with my mom! I couldnt meet Rosa but I met her brother Juan, he assisted us to the apartment :) I took taxi from the airport to the Plaza de Sanfrancisco, and met Juan around there.(Quiet hard to find out the apt yourself in the first time, so its better you have the meeting point somewhere like me.) The apartment is quite inside the street but nearby Iglesia del Salvador, only 3min walk. Apartment is really cozy and comfortable like my real house and fully equipped(kitchen, bedroom washroom , everywhere were in good condition, AC, Heater system and wifi was great as well! ) Every tourist places were in walking distance, minimum 5min to maximum 15-20min.
We enjoyed Flamenco show in the Flamenco Dance Museum which takes only 5min from this apt(you can make a booking through website or from this place itself), and also found nice place for TAPAS nearby this apt, named "Sal Gorda" , my mom and I really liked it !
We really loved staying in here :)
