This was a very homely apartment, with a great feel to it and we loved our stay. Maria's communication and response rate was excellent, the check in a breeze and she was very accommodative when we arrived early and departed late.
The apartment was very well located and we could walk to everything we wanted to see (and even to the train station). There are three supermarkets within 3min walk from the apartment.
The apartment is designed such that the rooms face away from the street and they were very quiet - probably the most quiet sleeping space we had after 4 weeks of travelling through Spain.
The wifi was excellent and I could work (with VC) and stream video with ease and with no interruption at all.
The AC worked very well. While we were there the temperature was over 40 decrees celsius every single day, yet the apartment was comfortable all the time.
We would not for a moment hesitate to stay in Maria's apartment again should we ever return to Seville.
