I wouldn’t stay here again.
1. This is not a “boutique hotel”, it’s a hostel.
2. I never received any kind of check-in instructions, and the host never responded to any of my messages. Finding the place was difficult and fortunately I could use broken Spanish to ask the receptionist to come down and help us in.
3. The hostel reeks of something that I can only describe as the cheapest incense and children’s dollar store perfume. The smell is so strong I could barely sleep.
4. Not the cleanest. There was someone else’s hair on the side of my shower when I first got in.
The positive:
It’s pretty central, just a short walk to the Prado museum, Gran Via street, the park, and all the nightlife (just don’t expect a quiet sleep in you’re not into that).
