This place is great for large groups as it had enough space for 8 people. The aircon was a life saver as it was a scorching summer. And it’s in all the rooms. The place has all necessary amenities except a washing machine but there is a laundromat literally downstairs.
The check-in people were amazing and answered questions within ten minutes. We even got little munchies left for us, some coke and salami as a little welcome gift :)
The location is also good. Not in the central hub of it all but close enough by metro or taxi to get to most places. There is a cute park close by which was great for summer walks and hanging out.
I would recommend staying here if you are in a large group and want to explore Madrid.
Be warned- there are two flights of stairs which, if you are fit are no problem but could be an issue for the unfit. Lovely stay and great host!
