Vivian's place was a perfect spot for two of us to enjoy Barcelona. The location was very close to common tourist spots while still allowed us to experience living in the city of Barcelona instead of surrounded by a high density of tourists.
The apartment is located off the street with windows opening to the terrace in the courtyard, so noise level was low. The apartment is super cutely decorated, as shown in the pictures, and the quality of appliances was high. The air conditioner worked well, although wasn't always needed as the studio stayed relatively cool and we were able to enjoy being out on the terrace. The shower was also amazing.
Vivian was waiting for us when we arrived. She also responded quickly to our requests. Overall, I'd definitely stay again at Vivian's place.
