The location is great and the space was comfortable. It's a great value for staying very close the the Grand Via! Remember that the value for the cost is what we use to gage a review and the cost is much more affordable. We weren't expecting pristine and free of clutter. With three of us staying there we felt a bit cramped but that's what we expected.
Our flight into Madrid got canceled and we ended up stuck in London, so we missed one of the two nights. Airbnb representatives asked Carlos if he would consider refunding some of our first night since we were unavoidably delayed a whole day. He was well within his rights to decline and he did, so we paid for 2 nights and stayed one. We understand. It's not his fault that ice storms locked up all flights from Heathrow. Still it might have been nice to have a partial refund.
Overall, a good place to stay to be in a great location for not a bad price. Thank you!
