Quim and Isabel are great. They live across the hall. The building is old and small and the apartment is plenty of space for a family. The location is ok — it’s definitely a hike from the city center and about 10 min walk to Atocha but it’s perfect if you don’t have small kids, don’t want to be right off/on Gran Via and want to walk to all the major sites. The building itself was very hot in common areas but I was there during an extreme heatwave. Taxis are easy to get on the street. There are four full bedrooms and three full baths. The baths are very tiny with no storage but they’ll do just fine. There’s no dryer (common in Spain) but there is a dishwasher and plenty of dishes etc. All the standard amenities like shampoo were included. Best of all the hosts were responsive and even helped us get a babysitter. So pretty much they were awesome. If I were coming as a couple I’d want to be closer to Gran Via/Plaza Mayor but it would be more expensive and difficult with small kids so this place was a great compromise.
