In general, Jorge's place is fine... it's nice and spacious, the beds were comfortable, and the kitchen was ample for our needs. The location is amazing—right across the street from the old part of town, where you can walk everywhere. The shower, while small (it's Europe, after all!) seemed to have enough hot water for our five adults (some showered at night to be safe).
Clarification on the photos: We weren't sure how the apartment was structured so just wanted to be clear here for future renters. The day bed you see in the photos pulls out, so it turns into a queen. The futon in the living room is comfortable enough for sleeping, and there is another queen and small twin upstairs. So basically there are two, two-person beds, a futon that could sleep two, and another small bed that could sleep one.
I have a very hard time writing negative or even neutral reviews, but thought it important in this case. As other reviewers have said, the WiFi is unbearable. In fact, it stopped working entirely 2 days into our trip, and Jorge didn't respond to two different messages asking for assistance. We also ran out of toilet paper—while not a big deal (we just ran to a local market to get more), it would have been nice to get a response to find out whether or not he had more stored somewhere. We also had a hard time with there only being one set of keys, and not being able to lock the door behind you without the keys—when traveling with a group of five, most of whom did not have consistent access to data or WiFi, it was hard to communicate about who was going to be at the apartment and when, so we could get let in and out. (This makes siesta very difficult! :))
If you're traveling with a group that will always be together, and you don't care about WiFi, this place would be just fine for you. Thanks to Jorge and his father for hosting us. We love Seville.
