We stayed as a group of 7 with three young kids (4-8 years old).
The apartment is in a great location, in a buzzy, vibrant residential area called Triana - there’s a number of good places to eat and drink on the doorstep including the Food Market.
The centre of Seville is easily walkable even for the kids, although the bribe of an ice cream from the Gelateria near the apartment when coming back always helped.
The apartment itself was as described, clean, comfortable and never felt cramped.
We would happily return again
Marked 4* and not 5* for 2 reasons:
I) The bathrooms were clean, but there wasn’t a lot of privacy/noise-reduction. In fact, when using both bathrooms at the same time, you could hear every bit of noise in the other
II) In general the doors/walls are all very thin. We slept well, but are all fairly heavy sleepers. Despite being on the second floor, you do get a fair bit of noise from refuse trucks and people in the restaurants across the road.
