Olga and Sergio's apartment was awesome! Communication was always great and checking in and out was easy. The apartment was very spacious for two of us, extremely clean, bed was comfortable, and the kitchen was more than well equipped. There was also a washer which we made use of. One day we stayed in since it was raining and it truly felt like home. The apartment is also located in the super awesome area of Södermalm where there are tons of little restaurants, shops, and bars. There is also a great Chinese dumpling place around the corner. Delicious! You can also easily walk to Gamla Stan in about 15min time. We didn't meet Olga, but instead communicated and met with Sergio. He was extremely helpful, pleasant, and available throughout our entire stay. We highly recommend this apartment. Next time we are back in Stockholm, we will definitely try to stay here again!
