Lovely little flat in a great location. We stayed for 2 nights with our 2 girls aged 8 & 6, it was perfect for us. And I loved the clean smell of the place as we walked in. The stairs are narrow to get to the flat on the 2nd floor, so like what other guests have said a carry on luggage is fine but a large and heavy one would be a bit more tiring to get up. I would just add that the second bedroom is up another narrow spiral staircase which is on top of a metal frame so it could be a bit detached and away from the other bedroom and may not be so convenient if your little ones tend to wake up at night. The communication was great, very prompt and helpful. We would book this again if we came back to Sevilla.
