We spent 4 nights during the "semana santa " in Marta's place. The best of this apartment is the location : great tapas restaurants just with 5 mns walk, supermarket on the Street, 2 between 2 subways (Sol and Latina), Plazza Mayor (5 mns walk)...and all the processions around on the evening. You don't realize you are in the center when you are in the apartment or the terrace, it's completly quiet...so it's really perfect ! The communication with Marta was easy, she answers very quickly and in English if you need. The check in with the locker is useful... So...it's was great !!!
