We spent a month in Virginia & Ignacio's place in April 2019. We stayed with our six month old baby, and Ignacio provided a travel cot and highchair (the highchair was a bit too old for our baby so we couldn't use it but it would have been great for a slightly older child).
The apartment is beautifully styled and the artwork is very special, along with the great light from the floor to ceiling windows. There is plenty of storage space, and lots of towels and sheets were provided. The kitchen was exceptionally well-equipped and was a joy to use.
I would thoroughly recommend the apartment if you are looking for somewhere comfortable and stylish in a good location - it wasn't in a touristy area but was very near all the sights.
I tried to join the gym mentioned in the listing and photos, but they weren't really set up for short-term visitors, far better is Cuesta Sport which allows a week or month membership - but it is a 15 minute walk away. I also really recommend the cheese shop on the next door street; amazing coffee!
If you're visiting Seville and plan on spending your nights out - enjoying tapas and the local late-night culture - then this apartment would be perfect. However, if you're with a baby and need to spend nights in in a quiet environment then this might not be for you. It may be true for lots of places in Seville - but the apartment, despite being on a residential street, had one bar opposite in which just a few people made a lot of noise until about midnight each night. There were also recycling bins opposite, which were emptied late at night! And, the bus station (also opposite) causes noise with buses going in and out - and particularly all the wheelie suitcases being pulled along the bumpy street. But, if you're out and about in the evenings, then this shouldn't bother you at all. It just wasn't ideal with a baby.
