Let us start with the positive. This apartment is centrally located and the building and space are lovely. The terrace was great and you had a nice view of La Giralda. It is very clean and had a washer for us to wash some clothes while we were there. The terrace served nicely to hang the clothes to dry.
First major problem: in the second bedroom (with a futon bed) on the 3rd floor, the air conditioning broke and though the owners brought a fan, 42 degree weather that day made that floor inbearably hot. We had to relocate to the sofa bed in the livingroom as sleeping with the windows open, coupled with the ringing from the Giralda every 15 min, made sleeping impossible. (Please note: normally the ringing would be charming but not with windows open and when sleeping is already difficult because of the lack of air con).
2nd major problem: inconsistent or no hot water. The master bedroom bathroom had more hot water but it was inconsistent. It went hot and cold randomly and it made for an incomfortable shower. Also only one person could use the hot water at a time (shower or sink) or the water temperature was greatly affected.
The 3rd floor bathroom had NO hot water at all. All members of our party had to share the master bedroom bathroom during our stay.
We specifically looked for a 2 bedroom apartment with at least 2 full bathrooms and ended up with a 1 bedroom and 1 bathroom suite. We would not have booked if we knew the troubles this apartment was having.
Buyer beware.
