Hugh's studio is a great place. I stayed here while visiting Seville for a few days. The unit was quiet and comfortable. I was able to make a few simple meals in the kitchen. The location is pretty central as I was able to walk to the cathedral in about 15 minutes. There are lots of cafes nearby in Alameda de Hércules. Hugh was very responsive.
The terrace was nice especially the view of the city. I did not use the terrace much though since my visit was in winter. I imagine it would get a lot of use in summer.
Note: The unit is four flights up with no elevator, so be prepared.
