We stayed four nights and mainly booked this place because of the location and the parking space. Both was great, but only small cars are possible in this garage. With our VW Polo it was challenging to get in :)
A nice plus was also the free bikes. The seats were not comfortable but for a few hours to see the not that central parts of the city it was very nice.
What we also liked about the apartment was, that it was really spacious for two people. What is missing is the daylight, which mainly comes through the entrance. As the apartment is formed like a long garage, it is pretty dark during the day. At two days we smelled the kitchens and food of the neighbors and also heard them very loud around 11 p.m.
All in all we were happy for the four nights! Maria is totally easy to communicate with and provides nice advices where to go in Seville.
