4 Bears runs as a well-oiled machine that is also very cozy and homey. It is in a great neighborhood and close to Tirso de Molina Station for easy accessibility. Don’t worry if you don’t see a sign out front like other hostels. It is exactly where Google maps will take you. Just follow the directions sent to you to go inside and you will be very pleasantly surprised. I absolutely would stay here again and already booked a second stay to extend my time in Madrid.
