Allison is a great host and her son (who did majority of the translating) is such a great kid! He knows three languages and is very intelligent. The apartment is clean, very well equipped, neat and tidy, and comfortable. Allison actually owns the entire building and lives upstairs, so she is always just a few steps away if you need her. The location is pretty tucked away and is in a relatively newer part of the old Sevilla. About a 7-10 minute walk from central Sevilla near the cathedral.
There was only one issue which caused my boyfriend and I to move to a hotel after the first night of our two night stay. The apartment is located on the first floor of a pretty narrow street, which consequently has three pretty popular outdoor bars. One of which is right below the bedroom on the adjacent building. It was a Monday night, but the chatter was very loud and the last bar closed at about 4am. We didn't fall asleep until then. At 8am we were again woken up by street construction about 100 yards away. The construction was lifting about 2 feet of cobble stone, so it was jack hammer loud and weren't don't when we checked out at noon. We do not blame Allison for not warning us of this this because I don't think she knows the extent of the noise since she's at work before construction starts. So, we didn't stay our second night cause we were exhausted from traveling and lack of sleep.
Again, this is a great apartment and they may be done the construction by now. I would still recommend staying here, but highly suggest ear plugs for those late night bars.
