Communication with Nacho is very good, he is friendly and ready to answer any questions. He was also flexible when we had to check in a little earlier than originally planned. Before our stay he gave us detailed instructions as for how to find and use the keys to the studio.
The studio itself was also exactly what we expected upon booking. Great location near the city center, complete bathroom, living area & kitchen, comfortable bed. Perfect for 2 people. Our only caveat was that the cleaning in the bathroom upon arrival could have been a bit more thorough, but it did not negatively influence our stay.
Overall we were very pleased with our stay in Sevilla, the studio was a nice place to come back to between various trips and adventures :)
