Had a fantastic stay at Benigno's flat a short walk from Gran Via in Malasaña/Chueca. Brilliant location to explore from with fantastic for shopping - vintage stores and luxury goods.
The apartment is well-equipped too with great furnishings and everything you need in the kitchen if you fancy cooking.
Benigno was great at communication too, he let me drop my bags a few hours early as I was already in Madrid coming from another flat, and check out a couple of hours later as my flight wasn't until later in the evening.
Can't recommend this place enough and can't wait to come back to Madrid and visit again.
Muchisimas gracias Benigno!
