Best hosts ever! I'm from Iran, and Iranians are famous for their hospitality, therefore I have met numerous fabulous hosts. But Elena and Pachi were amazing! They were totally supportive, helped us in every way possible and greeted us great! I can say that they are bests hosts ever!
And about the flat, it's way more amazing than the pictures. The fabulous interior design, the complete set of kitchenware etc. It's really cozy, I really felt at home there.
The only problem with the flat is that the building does not have an elevator and the apartment is at the fourth floor. So if you have old people accompanying you, or you have cardiovascular or respiratory problems it may be a problem, otherwise, nope no problem at all.
So to make it short, both the flat and the hosts are great and this option is strongly recommended! I hope you can enjoy Madrid as much as I did! Do not hesitate to book this apartment if it's available.
